        Description



        Name: icR10030 Date: 04/27/2000


        The Hotspot VM both build 1.3.0-B and build 1.3-b12 for Solaris
        (both java and java_g) intermittently fails the test
                nsk/jvmpi/events/mncntenter001
        from
                testbase_nsk

        To reproduce the bug run Korn shell script
                doit.ksh <jdk_root_directory>
        in
                /net/sqesvr/vsn/GammaBase/Bugs/<this bug number>

        The script produces the output:
        java version "1.3.0"
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-B)
        Java HotSpot(TM) Client VM (build 1.3.0-B, interpreted mode)
