At least one of the Lucene tests is failing in 9b110, and the latest hs-comp:

See the "NOTE" line for the one-liner reproducer.

Fastdebug build does not assert. The test starts to pass with -Dargs="-XX:TieredStopAtLevel=1" or -Dargs="-XX:+UnlockDiagnosticVMOptions -XX:-FoldStableValues", which points to @Stable bug in C2. Dropping @Stable from String.value also makes test pass. This seems to be another thing triggered by @Stable String.value (JDK-8150180) -- we fixed a lot of them, but this one seemed to escape.
