We also want each component to be able to define how jtreg is invoked (problemlists, concurrency, agentvm, ...).  There is already some support for running jtreg tests from the <top>/test folder, but it is not general enough since it isn't possible to pick individual tests or specific test groups. It is also not possible to direct the output to a common location.

The challenge here is choose between the conflicting goals of simplified 
large test runs that someone might want to do on a dedicated machine, 
and a fragmented run such as you might want to do on a test farm.
