I've recently started to run the regression on tests on a 96MB machine with 12 cores. Unfortunately with high concurrency then the tests crawl on this big machine.

One of the culprits is the keytool tests. Running with say -concurrency:8 that lead to 8 instances of keytool running and as the tests seem to ignore the VM options specified to jtreg then it means that each instance attempts to reserve 1/4 physical memory.

This bug asks for the security tests that run keytool, jarsigner and other tools to pass through the VM options consistently.
