One of our automated tests ran into this exception:

When debugging, I can reproduce the following two stack traces on the same ResourceInfo object:

To reproduce:

  1. Debug Eclipse in a new workspace.
  2. In the debuggee, create a Java project with a source file:
package test;

public class TestClass {

	public static void main(String[] args) {
//		int x;
	}

}
  1. Set a breakpoint at the return line of: org.eclipse.jdt.internal.ui.text.correction.CorrectionMarkerResolutionGenerator.internalHasResolutions(IMarker)
  2. Set a conditional breakpoint at the start of: org.eclipse.core.internal.resources.ResourceInfo.setMarkers(MarkerSet), the condition is: value == null
  3. In the debuggee, comment in the line: // int x;
  4. In the debuggee, comment out the same line, this will hit the breakpoint in: ResourceInfo.setMarkers()
  5. In the debuggee, expand the only collapsed row, this will hit the breakpoint in: CorrectionMarkerResolutionGenerator
  6. Set a breakpoint at: org.eclipse.core.internal.resources.ResourceInfo.getMarkers(boolean)
  7. Resume the main thread that is in CorrectionMarkerResolutionGenerator, this will hit the breakpoint in: ResourceInfo.getMarkers()
  8. You should now see the two stack traces from above, on the same object.
  9. Step over in the AutoBuildJob thread.
  10. Resume the main thread.
  11. Observe logged error.
