      Description

      ###@###.### 2003-09-21

      During my NSK testing run using a Tiger-B20-snapshot VM dropped into a
      Tiger-B19 JDK, I observed a hang in the following NSK tests in most of
      my configurations:

          nsk/jvmpi/events/mncntenter001
          nsk/jvmpi/events/mncntentered001

      The mncntenter001 failure reproduced 15 runs out of 16 and mncntentered001
      failure reproduced 4 runs out of 16. The repro runs were on Solaris SPARC
      with java -client-test -Xmixed bits. truss output shows the VMThread and WatcherThread running and no other thread activity.


      ###@###.### 2003-11-12

      During my Tiger-B28-snapshot test cycle, I observed a hang in the
      following NSK test:

          nsk/jvmpi/events/mncntenter002

      ###@###.### 2003-11-26

      It looks like this hang also occurs in the following NSK test:

          nsk/jvmpi/events/mncntexit001
