Bug 61709 NPE in JUnit view plus strange behavior
I200405060200 + plug-in export for I200405110800 I was running two JUnit plug-in tests from two different workbench window (maybe I switched to early from one window to the other). I then saw very odd behavior: the JUnit view switched showing results from both tests (see attached picture which shows that the jdt.ui.tests are run but a result from the refactoring tests is reported (below title). The cause for this might be the following NPE(?):
org.eclipse.jdt.junit/src/org/eclipse/jdt/internal/junit/ui/TestHierarchyTab.java
return;
			parentInfo.setStatus(ITestRunListener.STATUS_ERROR);
			testRunInfo.setStatus(ITestRunListener.STATUS_ERROR);
		}
		propagateStatus(parent, status);
	}
	
	private TestRunInfo getTestRunInfo(TreeItem item) {
		return (TestRunInfo)item.getData();
	}
	public void activate() {
		fMoveSelection= false;
		testSelected();
	}
	
	public void setFocus() {
		fTree.setFocus();
	}
	public void aboutToStart() {
		fTree.removeAll();
		fSuiteInfos.removeAllElements();
		fTreeItemMap= new HashMap();
		fCachedParent= null;
		fCachedItems= null;
		fMoveSelection= false;
		fExecutionPath= new ArrayList();
	}
	
	private void testSelected() {
		fTestRunnerPart.handleTestSelected(getSelectedTestId());
