For test automation purposes we require a way to run jtreg tests for the different components (jdk, langtools, jaxp, hotspot, nashorn) in a unified way from the command line. 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.
