The SAP Extension Suite (formerly part of the SAP Cloud Platform) is a legacy solution that enabled businesses to rapidly build and enhance applications, processes and experiences, with the goal of driving agility and flexibility, while extending the value of applications. The product has obsolesced, and modern offerings including SAP Build or the
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 Java Swing (UI toolkit) is now rather outdated, lacking support for modern UI features.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.
The adoption of SAP Extension Suite is growing significantly and it has become a strategic platform for our company. SAP Extension Suite will most likely meet the requirements of most companies to get beyond small workgroup apps and tackle more strategic requirements. The most important thing that SAP Extension delivers is a single UI for development effort for web and mobile deployment.
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.
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.
We have been able to work in a much more agile way with SAP Extension Suite, and there is a lot of excitement that developing with this platform is significantly faster. SAP Extension Suite is the perfect fit to build great-looking applications that work on any form factor, be it [a] smartphone, laptop, or tablet, and within budget.
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.
