> 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
