RFR for JDK-8019502 some java.util test does not pass VM options when launching java program in script

[Patrick Zhang]

Hi Everyone,

I am working on https://bugs.openjdk.java.net/browse/JDK-8019502. The 
problem is, some java.util test does use ${TESTVMOPTS} to launch java 
program in script. Then it may lose VM setting from high level.

The fix will refer to https://bugs.openjdk.java.net/browse/JDK-8003890 
finished by Mark Sheppard. Just add ${TESTVMOPTS} to launch java.

Regards
Patrick
