        Description

        The JVM dumped core while doing some auto-completion in NetBeans 7.0. Only seen once so far.

        Here's what the top section of hs_err_pid says (the full file is attached):

        #
        # A fatal error has been detected by the Java Runtime Environment:
        #
        # Internal Error (c1_Optimizer.cpp:271), pid=20031, tid=7
        # guarantee(x_compare_res != Constant::not_comparable) failed: incomparable constants in IfOp
        #
        # JRE version: 7.0-b139
        # Java VM: Java HotSpot(TM) Client VM (21.0-b09 mixed mode, sharing solaris-x86 )
        # Core dump written. Default location: /home/kh160127/core or core.20031
