Kelly was talking about separate processes running separate copies of
jtreg for disjoint segments of the test suite. That is safe, and can use
samevm/othervm as long as the tests themselves don't interfere with each
other on shared system-wide resources such as port numbers.
For my part, I was talking about the basic JavaTest facility to run
tests concurrently using multiple threads in the same JavaTest VM (using
either the -concurrency command line option or the "concurrency:" field
in the GUI). That works for JCK, subject to the inherent
test-interference rule -- for example it works for JCK compiler tests.
jtreg does not support this level of concurrency.
Sorry for the confusion.
