Modern development has become faster and reusable with long-term support and rich language features

April 01, 2026
Review from a verified AWS customer

What is our primary use case?

OpenJDK Java is one of the open-source Java development kits that I use. With all the Java libraries included in the JRE, I can handle all cases regarding object-oriented programming. However, it does not include J2EE (Java Enterprise Edition). OpenJDK Java is used for Java development and can be utilized in Spring Boot, Spring framework, and other play frameworks.

OpenJDK Java provides nearly all the functionality that Java uses. When comparing OpenJDK Java to Java EE, OpenJDK Java offers better code reusability through OOPs features, class collections, and collection frameworks. These features also bring some J2EE capabilities through beans. A main feature is that OpenJDK Java has Long-Term Support (LTS). For example, Java 21 has long-term support, and Java 1.8, Java 11, and Java 17 also have long-term support. Additionally, there is no cost for development, whereas Java EE is a paid feature where beans are handled by Java. From Spring Boot and Spring framework, I can use OpenJDK Java effectively.

OpenJDK Java runs on Windows, Linux, and macOS across every type of operating system. Similar to Java, OpenJDK Java compiles with Java code into bytecode, which runs in the JVM machine. All the features included in JEE are already present, such as Java compile code, Java run program, Javadoc, and job running and debugging. Multithreading is supported by OpenJDK Java. These are powerful tools, and high performance is available. JIT compilation and adaptive optimization are also present, along with regular updates as a main feature.

Java typically updates twice a year, with updates occurring every six months. Regular updates include bug fixes that do not impact the code if I use LTS (Long-Term Support). If a small update comes, that is fine. If a big update comes, I can also handle it. LTS support will always be available as a key feature. Currently, Java 21 has LTS support, and any update that comes will support my code.

What is most valuable?

OpenJDK Java can be used for Java development in Spring Boot, Spring framework, and other play frameworks. OpenJDK Java provides code reusability through OOPs features, class collections, and collection frameworks. Long-Term Support exists in OpenJDK Java for versions such as Java 21, Java 1.8, Java 11, and Java 17. OpenJDK Java runs on Windows, Linux, and macOS. It compiles with Java code and supports multithreading, high performance, JIT compilation, and regular updates.

What needs improvement?

Bean optimization could be improved. When comparing Java 1.8, which has a basic structure with for loops, to the stream API, the libraries are beneficial but slower. A for loop is a single loop that runs at the core level, whereas the stream API does the same thing but with slightly lower performance. Several improvements could be handled: performance improvement, better garbage collector latency, cloud container awareness, and cleaner syntax. Additionally, lambda is complex for beginners, so the usage of lambda could be improved.

The world is moving toward generative programming and AI usage with agentic approaches. Developers should have better handling of automatic GC performance issues. When compiling anything and an error is thrown, I want developers to have better performance insights into how this error will occur. Through AI, they can debug more effectively. Currently, when errors come, they are not straightforward. Developers have to read between the lines. If AI explains the error response, that would be better. Additionally, code usability could benefit from AI agentic capabilities.

For how long have I used the solution?

I am currently using OpenJDK Java.

What do I think about the stability of the solution?

I do not think there are any stability issues. Java has a very large community, so if anything comes up, I am able to resolve it. In this AI era, most issues can already be resolved. I do not believe any challenges have come that cannot be overcome.

What do I think about the scalability of the solution?

I do not think there is any scalability issue in OpenJDK Java.

How was the initial setup?

I do not think there are any challenges with initial setup. However, when installing any application, everything should be set up automatically, similar to how Java is installed. There should be no need to write environment variables. They should already be set up in the system. At the beginner level, developers can only write the code and do not have to use environment variables at all.

What's my experience with pricing, setup cost, and licensing?

The API impact on OpenJDK Java is minimal. When using the Spring Boot framework or similar frameworks, most things and beans are handled by the Spring framework. OpenJDK Java supports method level functionality with no difference from J2EE. However, bean handling can be a consideration because J2EE handles beans more efficiently compared to other frameworks. J2EE uses better bean optimization. Apart from this, I do not think there is any other issue. Most libraries already support both J2EE and OpenJDK Java, so I do not think there is any other impact.

Regarding development impact, performance-wise, OpenJDK Java is faster. One of the best features is that I can change my code and create my own compiler. Whatever method I choose, I can modify the code in JIT within OpenJDK Java. This is not possible in J2EE as J2EE does not allow these things. In Java 1.8, I can also change the background code and library code as this is allowed.

What other advice do I have?

OpenJDK Java is open for everyone, every developer, and every company, and it is free of cost. There is no deployment cost or any such pricing. OpenJDK Java can be used for developing any type of software that uses API level functionality, such as backend software. I gave this review a rating of 8.5 out of 10. If a company is choosing Java tools, they should go for OpenJDK Java.

Centralized development has delivered fast, secure payment processing with strong community support

March 31, 2026
Review from a verified AWS customer

What is our primary use case?

OpenJDK Java is used centrally for developing back-end services like APIs, batch processing, and file processing. It is easy to integrate OpenJDK Java with any other product or other languages regarding cross-platform capabilities.

What is most valuable?

What stands out for me about OpenJDK Java is that it is good for processing fast and very efficient in memory management from a technical perspective. It is fast, reliable, and easy to develop any concept in the payment industry.

The community support in OpenJDK is very helpful for my development process. The community has helped me with information on the latest features they added, new encryption and decryption methods, and how the internal memory works. These are the pieces of information I can get from the community channels.

I see a benefit from the regular updates in OpenJDK, as it is beneficial when we face many challenges in development. The regular updates from Oracle provide patches to solve different challenges in terms of security and memory management. From a developer's point of view, it also makes tasks easier.

What needs improvement?

Regarding OpenJDK, I do see areas for improvement, though I cannot currently comment on potential improvements. I acknowledge that there is a chance for enhancement.

Comparing OpenJDK Java with Python and other scripting languages, I find it a bit bulky, as it takes a lot of effort to enable scripts in a system. While Python is good for small tasks and easy to deploy, OpenJDK Java requires more effort for similar tasks.

For how long have I used the solution?

I stopped using it in March 2025, which is more than a year back now.

What do I think about the stability of the solution?

OpenJDK Java is 100% stable and demonstrates no downtime or glitches.

What do I think about the scalability of the solution?

OpenJDK Java is scalable.

How are customer service and support?

Community support is available, and there is also technical support with many discussions happening in different communities since it is an open platform, offering a lot of assistance. In my case, community support has been sufficient, and I did not need to reach out to technical support for the product.

How was the initial setup?

Installation for OpenJDK Java is easy, with not much complexity in the steps.

What was our ROI?

I can observe savings in my ROI and categorize it as money-saving. If I quantify the savings, I see about 60% in money savings and 40% in time savings.

What's my experience with pricing, setup cost, and licensing?

In terms of licensing and pricing for OpenJDK Java, I find it affordable and not expensive.

What other advice do I have?

I have experience with TiDB Cloud as I have been using that product before. I am working right now with multiple vendors and not only with a particular database, as I am using front end and back end languages including React and Angular. I am currently writing some Python code and back end Java.

The languages I am using include Angular, React, Java, and Python. PowerCARD is the product I am currently working on, which is a card product and an HPS product.

I am using OpenJDK Java and confirm that I use OpenJDK Java. I have around 10 plus years of experience with OpenJDK Java. I work with the product not only as a user but also as a consultant, working as a consultant with the vendor.

APIs impact my development speed positively as it is fast and secure, and it is easy to integrate across platforms with different tools and technologies. Almost all the tools available in the market are Java JDK enabled, making integration with OpenJDK Java very easy.

The cloud-native capabilities in OpenJDK Java are beneficial for my projects, as about 80 to 90% of the projects I work on in the card and payment industry are running on OpenJDK Java. I work in a hybrid environment, using a mix of cloud and on-premises solutions.

I have solutions available on AWS Cloud, and OpenJDK Java is compatible with AWS and Azure, as I use both. As of now, I have not purchased anything from the AWS marketplace.

I give this review a rating of 8 out of 10.
