There is a problem with jtreg usage under MKS. By default, comparison case statements in MKS are case-insensitive. This means that -javacoptions is matched with -J* and thus is recognized as java option, added to java command line and causes jtreg to fail:

Unrecognized option: -javacoptions:
Could not create the Java virtual machine.
