Thanks Brian,
With Eclipse OpenJ9 you see this, which is very similar to if you force
Hotspot with -XX:-CompactStrings:
Exception in thread "main" java.lang.OutOfMemoryError

-XX:+CompactStrings
Hi Andrew,
I can help you. The change looks good but what do you see when you run the
test without the change on a non-Hotspot VM?
Thanks,
Brian

Please can I get a sponsor and reviews for the following "patch" to the

The current testcase makes the assumption that -XX:+CompactStrings is the
default, which it is for Hotspot, but that's not necessarily true for all
JVM providers.
