On Vista 64-bit machine, interoperability/rmiiiop run with matrix "tiger mantis ripint", testcase failed at "mustang_x_mantis" "mustang_x_ripint"

Test can be reprodeced with
/net/koori.sfbay/onestop/jdk/6u10/promoted/all/b14/binaries/windows-i586
/net/koori.sfbay/onestop/jdk/6u10/promoted/all/b05/binaries/windows-i586

How to reproduce:
================
Map driver to access /net/sqenfs-1.sfbay/export1/comp/jsn/idl/rtm-generic-mustang-exec

Set following env:

TESTBASE=Q:/comp/jsn/idl/rtm-generic-mustang-exec
TESTSUITE=interoperability/rmiiiop
INTEROP="tiger mantis ripint"

TEST_JAVA_HOME=Q:/jdk/jsn/koori/6u10/promoted/latest/binaries/windows-i586
JAVA_HOME_MUSTANG=Q:/jdk/jsn/koori/6u10/promoted/latest/binaries/windows-i586
JAVA_HOME_RIPINT=Q:/jdk/jsn/koori/1.5.0_15/latest/binaries/windows-i586
JAVA_HOME_TIGER=Q:/jdk/jsn/koori/1.5.0_15/latest/binaries/windows-i586
RIPINT_HOME=Q:/comp/jsn/tools/appserver/rip_int/1.0/windows
( which is /net/koori.sfbay/onestop/rip_int_generic/1.0/archive/b67/binaries/win )

WORK_DIR=my_workdir_path
PATH="${TESTBASE}/bin:${PATH}"

cd "${TESTBASE}/tests/${TESTSUITE}"
rip-make -env mustang -jdk $TEST_JAVA_HOME -interop "$INTEROP" -workdir $WORK_DIR -hotspot "-server" -v all
