Similar to the recent test fix for 8211092 [1], this change proposes to modify the test so that it's main method does not return until all threads, created by the test, terminate. This is important when run in samevm / agentvm mode.
The change avoids any potential issues where jtreg may attempt to "clean -up" these threads ( the clean up fails quite often as the closer thread can linger in blocking close ). http://cr.openjdk.java.net/~chegar/8211325.00/index.html -Chris. P.S. I'll fix some of the unrelated indentation issue before pushing, which have been deliberately omitted to avoid confusing the actual changes. [1] https://bugs.openjdk.java.net/browse/JDK-8211092
