      Description

      We've been seeing this exception in unit tests on Windows since HADOOP-1191 was committed. For instance in TestMiniMRClasspath.

      [junit] 2007-05-03 21:19:21,447 ERROR mapred.TaskTracker (TaskTracker.java:offerService(783)) - Caught exception: java.lang.reflect.UndeclaredThrowableException

      It doesn't seem to cause the tests to fail, but it is logged as an error when a TaskTracker is being shutdown.
