I tried to set the JTREG time out to 60 seconds, and the timeout issue could be reproduced. In `test/jdk/java/lang/invoke/defineHiddenClass/UnloadingTest.java`, there are 6 calls to the method `assertFalse(unloader.tryUnload())`. Each call to tryUnload() takes at least 10 seconds. So the 6 calls takes 60 seconds at least. If I set the regression timeout value to 70 seconds, the test still can pass. It implies the rest part other than tryUnload() is pretty fast. It looks like a regression introduced with the update for [JDK-8287384](https://bugs.openjdk.java.net/browse/JDK-8287384). I did not fine the cause yet. I will have more checking tomorrow. ------------- PR: https://git.openjdk.java.net/jdk/pull/8979
