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
treeItem.setImage(fTestRunningIcon);
	
		TreeItem parent= treeItem.getParentItem();
		if (fTestRunnerPart.isAutoScroll()) {
			fTree.showItem(treeItem);
			while (parent != null) {
				if (parent.getExpanded()) 
					break;
				parent.setExpanded(true);
				parent= parent.getParentItem();
			}
		}
	}
	public void endTest(String testId) {	
		TreeItem treeItem= findTreeItem(testId);
		if (treeItem == null)  
			return;
			
		TestRunInfo testInfo= fTestRunnerPart.getTestInfo(testId);
			
		updateItem(treeItem, testInfo);
		
		if (fTestRunnerPart.isAutoScroll()) {
			fTree.showItem(treeItem);
			cacheItems(treeItem);
			collapsePassedTests(treeItem);
		} 
	}
	private void cacheItems(TreeItem treeItem) {
		TreeItem parent= treeItem.getParentItem();
