A number of intermittent timeouts have been observed from tests using VirtualMachine.list() or the jps command to locate a specific java process.

In large test runs a number of attaching tests can be seen in the test logs.

This issue is being filed to explicitly create a stress test that can help identify the root cause of this condition.

In the meantime other simpler changes are being made to minimize concurrent test execution for possibly interfering tests.
Also, the direct use of ProcessBuilder to obtain a pid for a child process rather than searching the running java process with fragile command line matching.
