           Summary: ARM T2 JIT  java.util.concurrent.ExecutionException
                    during rewriter.stamp
           Product: IcedTea
           Version: 6-1.8.7
          Platform: arm
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Thumb2 JIT
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: xerxes at zafena.se


The dual-core arm natty-armv7l builder hits this exception in about 1 of 10
builds while using the Thumb2 JIT enabled Icedtea6-1.8 release for
bootstrapping.

This bug have so fair not manifest itself when running builds on the single
core squeeze-armv5tel builder that does not make use of the thumb2 jit.
