Josh Elser commented on HBASE-18255:
------------------------------------

+1 from me -- should prevent this from being a problem on Java7 and doesn't change semantics
of Java8

Thanks for putting the patch together, Vlad!

> In a few words, due to internal JVM 7 bug (which has been addressed only in Java 8),
HotSpot code cache can become full and after that ALL JIT compilations get suspended indefinitely.
 The default value for code cache size in JVM 7 is quite low: 48MB. It is recommended to increase
this value at least to 256MB (default in JVM 8).
> This BUG affects only 1.x
