> `test/jdk/java/lang/invoke/defineHiddenClass/UnloadingTest.java` defines > hidden classes and verify cases that a class loader is not unloaded using > `ForceGC::wait`. ForceGC::wait` defaults the timeout to 1000ms * jtreg > timeout factor, which is designed to work well to expect an object being > reclaimed, i.e. the boolean supplier returns true. On the other hand, if > the boolean supplier never returns true, the method returns after it timeouts > which may be long depending on the timeout factor. > > This PR adds a variant of `ForceGC::wait` to take a timeout parameter and > tests can specify the timeout to reduce the time it takes testing a strongly > reachable object not being reclaimed.
