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
updateItem((TreeItem)o, newInfo);
			return;
		}
	}
	/* (non-Javadoc)
	 * @see org.eclipse.jdt.internal.junit.ui.ITestRunView#selectNext()
	 */
	public void selectNext() {
		TreeItem selection= getInitialSearchSelection();
		if (!moveSelection(selection))
			return;
			
		TreeItem failure= findFailure(selection, true, !isLeafFailure(selection));
		if (failure != null)
			selectTest(failure);
	}
	
	/* (non-Javadoc)
	 * @see org.eclipse.jdt.internal.junit.ui.ITestRunView#selectPrevious()
	 */
	public void selectPrevious() {
		TreeItem selection= getInitialSearchSelection();		
		if (!moveSelection(selection))
			return;
		
		TreeItem failure= findFailure(selection, false, !isLeafFailure(selection));
		if (failure != null)
			selectTest(failure);
	}
	private boolean moveSelection(TreeItem selection) {
