> The patch does not apply cleanly to 11u, because it conflicts with non-
> backported cleanup change
> (JDK-8207211) in test/hotspot/jtreg/runtime/appcds/test-
> classes/ProtDomain.java. Manual merge in
> that test was needed.
> 
> The resulting 11u webrev:
>   http://cr.openjdk.java.net/~shade/8214827/webrev.11u.01/
> 
> Testing: new test, entire runtime/appcds suite; verified new regression test
> fails without patch
