Description
We need a test of the change from JDK-8166188 (ultimately pushed as JDK-8176100) that verifies a jweak dereference during G1 concurrent marking works properly. Writing a reliable test for this was waiting for new test infrastructure provided by JDK-8169517. Now that we have that, we can add the new test of the handling of jweak with G1.
