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. java.lang.NullPointerException at org.eclipse.swt.widgets.Widget.drawRect(Widget.java:763) at org.eclipse.swt.widgets.Canvas.drawRect(Canvas.java:170) at org.eclipse.swt.widgets.Display.windowProc(Display.java:6037) at org.eclipse.swt.internal.cocoa.OS.objc_msgSendSuper(Native Method) at org.eclipse.swt.widgets.Display.applicationNextEventMatchingMask(Display.java:5317) at org.eclipse.swt.widgets.Display.applicationProc(Display.java:5710) at org.eclipse.swt.internal.cocoa.OS.objc_msgSend(Native Method) at org.eclipse.swt.internal.cocoa.NSApplication.nextEventMatchingMask(NSApplication.java:92) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3833) at org.eclipse.jface.window.Window.runEventLoop(Window.java:823) at org.eclipse.jface.window.Window.open(Window.java:799) at com.google.gapid.Main$UI.show(Main.java:136) at com.google.gapid.Main.main(Main.java:80)
Harsha, Thank you very much for reporting this. We will apply and test the fix(es) as P1.
Created attachment 285658 [details] 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.
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!
Fixed
