[11u] RFR: 8240676: Meet not symmetric failure when running lucene on jdk8

[Roland Westrelin]

Original bug:
https://bugs.openjdk.java.net/browse/JDK-8240676
https://hg.openjdk.java.net/jdk/jdk/rev/6ccf082f50d4

The 11u patch is unchanged but context in compile.hpp changed so the
original patch requires a small adjustment.

11u webrev:
http://cr.openjdk.java.net/~roland/8240676-11u/webrev.00/

Testing: x86_64, verified new test fails with the fix commented out,
works otherwise, tier1

Roland.
