        Description

        The testcase from HP (see below) reveals a HotSpot server crash related to loops. The crash can be avoided by setting LoopUnrollLimit=0. The test case has a huge jar. I will work with HP on trying to obtain the source and produce a smaller test case. The test doesn't fail with client compiler.

        The crash dump (reproducible with the latest mantis build: 1.4.2-beta-b04):
        #
        # HotSpot Virtual Machine Error, Internal Error
        # Please report this error at
        # http://java.sun.com/cgi-bin/bugreport.cgi
        #
        # Java VM: Java HotSpot(TM) Server VM (1.4.2-beta-b04 mixed mode)
        #
        # Error ID: 53484152454432554E54494D450E435050018D 01
        #
        # Problematic Thread: prio=5 tid=0x0002deb8 nid=0x1 runnable
        #

        TEST CASE TO REPRODUCE:

        0. cd /net/knight1/export/tmp/hp_loop_bug/

        1. Use ksh or bash

        2. "source setenv.sh"

        3. run myant

        4. after a couple of minutes a crash will happen

        ====================================

        HP's customer is not comfortable giving the source to Sun. So, I won't be able to deliver a micro test case.
