Please review this fix for a bug in JDK-8175797: the mechanism provided by that change for reverting to the old behavior of Reference.enqueue (for backward compatibility) does not work.
Also fixed the ReferenceEnqueue test changes also made as part of JDK-8175797. That test would havecaught the problem with the property but for bugs in the test. CR: https://bugs.openjdk.java.net/browse/JDK-8178832 Webrev: http://cr.openjdk.java.net/~kbarrett/8178832/jdk00/ Testing: Ran fixed test with unfixed enqueue, and verified expected failure. Ran fixed test with fixed enqueue, and verified expected pass.
