Can't init module exports: unexpected exception: java.lang.ClassNotFoundException: java.lang.JTRegModuleHelper

[Bysani, Keerthana]

Hi,

I recently ran the hotspot test suite on an OpenJDK Tree with a custom GC on May 30th and the stats show that around a 150 tests errored out.
When I ran the same tests again a few days back, the results reported that around 750 tests errored out because of:
Can't init module exports: unexpected exception: java.lang.ClassNotFoundException: java.lang.JTRegModuleHelper

This is the script I ran for testing:
#!/bin/sh
export JT_JAVA=/home/test/OpenJDKTrees/openjdk9-05-19/build/linux-x86_64-normal-server-slowdebug/images/jdk
/home/test/jtreg/bin/jtreg -g -jdk:$JT_JAVA -agentvm -automatic -verbose:summary -w build/jtreg/work -r build/jtreg/report -javaoptions:"-\
XX:+UseRtGC -XX:-UseCompressedOops -Xms256m -d64" hotspot/test

 Can someone please let me know where Im going wrong?

Thanks and Regards
