      Description

      Following nsk tests fails intermittently.

         nsk/jdi/stress/serial/monitorEvents002
              This test failed an assertion Linux IA32 Client VM (machine
              em64t-002); see addClassFilter_ReferenceType entry below.


         nsk/jdi/MonitorContendedEnteredRequest/addClassFilter_ReferenceType
              This test failed the following assertion:

                  Internal Error (src/share/vm/runtime/jniHandles.hpp:185)
                  Error: assert(handle != 0,"JNI handle should not be null")

              on Solaris SPARC Client VM (machine sys-ldom1-06). This failure
              mode matches an entry in the following bug:
      Another test failing this assertion in nightly:

      New nsk.quick-jdi failures (from 2008.09.17)
          nsk/jdi/stress/serial/monitorEvents001
              This test failed an assertion Solaris SPARC Server VM (machine
              toasteroven); see addClassFilter_ReferenceType entry below.
      Another test failing this assertion in nightly:

      New nsk.quick-jdi failures (from 2008.12.18)
          nsk/jdi/MonitorContendedEnterRequest/addClassFilter_ReferenceType
              This test failed the following assertion on Linux IA32 Server
              VM (machine vm-v20z-1):

                  Internal Error (src/share/vm/runtime/jniHandles.hpp:185)
                  Error: assert(handle != __null,"JNI handle should not be null")

              This failure mode is covered by the following bug:

                  6749729 3/4 fastdebug vm crashes due to bad jni handle passed
                              from backend when monitor events are enabled.

              I will copy this entry to 6749729.
