C2 compiler bug closed as incomplete

[Julien Nicoulaud]

Hi all, thanks for your answers.

I did some further testing and here is the results:
 - JDK 8u20-b05 : still crashes, but not always - logs at
https://dl.dropboxusercontent.com/u/62997/JDK-8038985/8u20-b05.zip
 - JDK 8u0 with -XX:-EliminateAutoBox : still crashes, but not always -
logs at
https://dl.dropboxusercontent.com/u/62997/JDK-8038985/8u0-no-EliminateAutoBox.zip

Also, since the crash always seems to occur while inlining Trove's
TCustomHashMap (http://trove.starlight-systems.com/) into my code, I tried
to:
 - Upgrade Trove from 3.0.3 to 3.1a1 (from
https://bitbucket.org/robeden/trove/downloads) => still crashes
 - Replace Trove by other hash map implementations => no crash

Regards,
Julien
