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[] sib= findSiblings(start, next, includeNode);
		if (next) {
			for (int i= 0; i < sib.length; i++) {
				TreeItem failure= findFailureInTree(sib[i]);
				if (failure != null)
					return failure;
			}
		} else {
			for (int i= sib.length-1; i >= 0; i--) {
				TreeItem failure= findFailureInTree(sib[i]);
				if (failure != null)
					return failure;
			}
		}
		TreeItem parent= start.getParentItem();
		if (parent == null)
			return null;
		return findFailure(parent, next, false);
	}
	private TreeItem[] findSiblings(TreeItem item, boolean next, boolean includeNode) {
		TreeItem parent= item.getParentItem();
		TreeItem[] children= null;
		if (parent == null) 
			children= item.getParent().getItems();
		else	
			children= parent.getItems();
		
		for (int i= 0; i < children.length; i++) {
			TreeItem item2= children[i];
			if (item2 == item) {
