Changeset: e680ebeb Author: Brent Christian <bchristi@openjdk.org> Date: 2020-12-19 00:17:02 +0000 URL: https://git.openjdk.java.net/jdk16/commit/e680ebeb

This change adds some extra test output for NativeLibraryTest, primarily via an update to the ForceGC utility class. It was observed that there was nothing preventing the Cleaner from cleaning the short-lived Object that ForceGC registers before await()/doit()/System.gc() is even called. The new 'o' reference is kept alive until FoceGC.await() has been called.
