Description Harsha Krishnareddy CLA 2021-02-24 14:27:39 EST 
OS version: MacOs bigSur 11.2
Java: jdk1.8.0_281.jdk (as required)
Eclipse: 2020-12 (4.18.0)


I am not able to run STEM in my OS environment. I tried setting up the development environment to investigate what's causing the issue. 

I have the `JAVA_HOME` environment variable setup - pointing to `jdk1.8` both globally and also in my STEM application's info.plist file, to make sure STEM is referring to java v1.8


I see a lot of `NPE error when initialize GLCanvas object` exceptions (bug 570649) on my console. A completely blank STEM UI loads up - some icons seem to be loading up intermittently, but the whole UI is un-responsive. 

Unhandled exception in the UI thread.

Patch for bug 571476

I managed to fix my problem and get stem to work properly on my Mac - bigSur. 

1. It seems like the dependencies defined as part of the stem4.target are fairly old.

2. A lot of the exceptions and problems seem to have been fixed either as part of the eclipse SDK or other packages. 

3. I update the target platform plugins/features to the latest versions and made a switch to use Java 11. 

This solved my troubles getting STEM to run in my environment. I created a patch with my changes for review.
Comment 3 Harsha Krishnareddy CLA 2021-02-24 16:54:26 EST 
After I made the changes to the target platform I had to cleanup my runitime-stem4.product outside my eclipse workspce -- just to make sure there are no plugin version mixups or dangling jar files in there!
