#  @test
#  @bug 4525714
#  @summary jtreg test PopAsynchronousTest fails in build 85 with -Xcomp
#  @author Jim Holmlund/Swamy Venkataramanappa
#  @key intermittent
#  @run shell DeoptimizeWalk.sh

#  This is another test of the same bug.  The bug occurs when trying
#  to walk the stack of a deoptimized thread.  We can do this
#  by running in -Xcomp mode and by doing a step which causes deopt,
#  and then a 'where'.  This will cause not all the frames to be shown.
