Description Andrey Loskutov CLA 2021-02-05 04:29:39 EST 
I can't compile my workspace anymore with I20210204-2320, I have lot of PDE can't resolve bundle XYZ errors and I see multiple errors in the log like

Java Model Exception: Java Model Status [org.eclipse.pde does not exist]
	at org.eclipse.jdt.internal.core.JavaElement.newNotPresentException(JavaElement.java:573)
	at org.eclipse.jdt.internal.core.JavaModelManager.getPerProjectInfoCheckExistence(JavaModelManager.java:2525)

	at org.eclipse.core.runtime.jobs.Job$2.run(Job.java:187)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63).

I20210202-1840 works. I suspect this is a regression from bug 569905.

The code in org.eclipse.pde.internal.core.MinimalState.loadWorkspaceBundleManifest(File, IResource) should check if the bundle project is a Java project before trying to get JRE from it.

I believe I have a patch (can't verify because my platform can't compile & debug right now).
