Amazon Corretto vs. Oracle Java SE

Amazon Corretto is the best platform for individuals, companies, or businesses to get started at no cost and easily develop and run Java applications in the same environment in the Cloud, on-premises, and/or on local PCs. Great support from AWS, solving all performance and security problems, and able to work on different platforms.

Oracle Java SE is well suited to long-running applications (e.g. servers). Java Swing (UI toolkit) is now rather outdated, lacking support for modern UI features. JavaFX, the potential replacement for Swing, has now been separated out of Java core. Ideally, there would be a path to migrate a large application incrementally from Swing to JavaFX, but due to different threading models and other aspects, it is difficult. At this point, it is probably better to use an embedded web browser (e.g. JxBrowser) to provide a modern UI in HTML/Javascript and keep just the business logic in Java.

• It incorporates the newest JDK version's security patches.
• It's helpful when testing hybrid deployments locally.
• It provides a significant advantage in terms of overall performance.
• It is especially useful because it gives us free access to the open JDK on any platform.

Incentivized

• Plenty support built into the tool and IDE like Maven, Ant, Eclipse, IntelliJ.
• Strong object-orientation language and clear project structure.
• Wrapper underlines hardware and memory management so the developers can focus on business and implementation.
• It offers a huge library and framework support from third-parties and the community.

Incentivized

• Amazon Corretto really has short documentation which has been the issue for us in the past resulting in the development issues
• This service is relatively unknown and less popular which results in the smaller community which means in case you get stuck somewhere it may be difficult for you to the find the resources.
• No other issues noted as of now by us

Incentivized

• Commercial Licensing in 2019. Oracle will charge commercial organizations using Java SE for upgrading to the latest bug fixes and updates. Organizations will now need to either limit their implementation of Java SE or may need to drop it altogether.
• Slow Performance. Due to the all of the abstraction of the JVM, Java SE programs take much more resources to compile and run compared to Python.
• Poor UI appearance on all of the major GUI libraries (Swing, SWT, etc.). Through Android Studio, it is easy to get a native look/feel for Java apps, but when it comes to desktops, the UI is far from acceptable (does not mimic the native OS's look/feel at all).

The language is fluent and has good support from a number of open source and commercial IDEs. Language features are added every 6 months, although long-term service releases are only available every 3 years. It would be nice if some of the older APIs were depreciated with more pressure to move to the new replacement APIs (e.g. File vs. Path), but transitions to new features are generally well implemented.

Java is such a mature product at this point that there is little support from the vendor that is needed. Various sources on the internet, and especially StackOverflow, provide a wealth of knowledge and advice. Areas that may benefit from support is when dealing with complex multithreading issues and security libraries.

Amazon Corretto is easy to use Open source JDK and very helpful to quickly get started at no cost with great support to build and improve application development on any operating system like Linux, Windows, and/or macOS. Highly available and reliable services backed by Amazon for the success of product development and good user experience.

Incentivized

Chose to go with Java instead of Python or C++ due to the expertise on the ground with the technology, for its ease of integration with our heterogeneous setup of production servers, and for the third party library support which we've found was able to address some challenging aspects of our business problem.

Incentivized

• Fixes & Patches getting delayed.

• The different versions make it harder to work with other companies where some use newer versions while some use older versions, costing time to make them compatible.
• Licenses are getting to be costly, forcing us to consider OpenJDK as an alternative.
• New features take time to learn. When someone starts using them, everyone has to take time to learn.
