    Description

      I ran HBase with "-XX:+PrintCompilation -XX:+UnlockDiagnosticVMOptions -XX:+PrintInlining" and then looked for "hot method too big" log lines.

      I'll attach a log of those messages.
      I tried to increase -XX:FreqInlineSize to 1010 to inline all these methods (as long as they're hot, but actually didn't see any improvement).

      In all cases I primed the JVM to make sure the JVM gets a chance to profile the methods and decide whether they're hot or not.
