      Attached java program fails(stucks in the dead loop) on linux-amd64 and solaris-sparc platforms
      with the following options:
      linux-amd64: -server/-client -Xcomp
      solaris-sparc: -server -Xcomp

      Without such options everything goes fine.
      I verified this bug with Mustang b71 and later.
      On Tiger such behavior isn't observed.

      Fastdebug build fails with the following assertion:
      # Internal Error (/BUILD_AREA/jdk6.0/hotspot/src/share/vm/opto/phaseX.cpp, 767 [ Patched ]), pid=10346, tid=8
      # Java VM: Java HotSpot(TM) Server VM (1.6.0-beta2-fastdebug-b75-debug compiled mode)
      # Error: assert(no_dead_loop,"dead loop detected")

      Tests which are affected(will be presented in testbase 16r05):
      runtime/ParallelClassLoading/delegate-system/dynamic-init/init-simple
      runtime/ParallelClassLoading/delegate-system/init-simple
