Using: JavaTest Harness 4.4 fcs b16
====================================

We sometimes see the following exception during tests tree update:

Exception in thread "Test Tree Cache Worker" java.lang.ArrayIndexOutOfBoundsException: 2
        at com.sun.javatest.ParameterFilter.accepts(ParameterFilter.java:78)
        at com.sun.javatest.exec.TT_NodeCache.process(TT_NodeCache.java:587)
        at com.sun.javatest.exec.TT_NodeCache.run(TT_NodeCache.java:92)
        at com.sun.javatest.exec.TestTreeModel$CacheWorker.run(TestTreeModel.java:1187)

as a result, tests tree updates gets interrupted and stops forewer.

Unfortunately if this situation happens the only is to restart the JT.

The TCK binary that I see the problem in can be found as:
