FULL PRODUCT VERSION :
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) Server VM (build 14.0-b16, mixed mode)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
A specific Scala method crashes when Hotspot tries to compile it but only when the following VM flags are set:
-server -XX:+DoEscapeAnalysis -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC

removing either EA or G1 prevents the crash

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the supplied Scala application

EXPECTED VERSUS ACTUAL BEHAVIOR :
The program should run without crash, the C2 compiler crashes

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Attached seperatly.


REPRODUCIBILITY :
This bug can be reproduced always.
