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
public SuiteInfo(TreeItem treeItem, int testCount){
			fTreeItem= treeItem;
			fTestCount= testCount;
		}
	}
		
	/**
	 * Vector of SuiteInfo items
	 */
	private Vector fSuiteInfos= new Vector();
	/**
	 * Maps test Ids to TreeItems. 
	 */
	private Map fTreeItemMap= new HashMap();
	
	private TestRunnerViewPart fTestRunnerPart;
