Test : nsk/jvmti/GetThreadGroupChildren/getthrdgrpchld001
VM : ClientVM, ServerVM
Mode : -Xint, -Xcomp, -Xmixed
Platform : x86, sparc, sparcv9
OS : SunOS 5.8, RedHat Linux 8.0, Windows 2000
JDK : 1.5.0-b14 promoted (JVMTI v71)
                  1.5.0-b15 w/ Hotspot build 20030820101708.rfield.hotspot3-product (JVMTI v0.2.90)
----------------------------------------

This test invokes JVMTI function GetThreadGroupChildren()
for three thread groups with the same number of threads:

    - group with not yet started threads
    - group with running threads
    - group with already finished threads

For the first two groups this function returns correct list
of threads, while for the third group the returned thread list
is empty.

This failure is reproduced either with JVMTI v71
and JVMTI v0.2.90.

To reproduce the failure for JVMTI v0.2.x:
  cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME [-g]
  sh run.sh $JAVA_HOME [-g] [-v] [JAVA_OPTS]
where
    -g - run test with java_g binaries
    -v - run test in verbose mode

Here is test output:
