failures running dyn tests with jtreg on mlvm

[Stephen Bannasch]

I'm getting new failures running the dyn tests in mlvm.

Seems like the  -XX:+UnlockExperimentalVMOptions -XX:+EnableMethodHandles are being passed into junit.

$ jtreg -jdk:build/bsd-amd64/j2sdk-image -v:verbose jdk/test/java/dyn/InvokeGenericTest.java

----------messages:(3/275)----------
