When running specjbb with -Xrunhprof:heap=dump on sparc, the assert
"thread has not dumped its register windows yet" fires based upon
pd_post_Java_state_has_flushed() results.

Note: Hotspot will run other test cases with the -Xrunhprof:heap=dump
command line option without getting the assertion, plus no apparent
problem is found when running specjbb with a product version of the VM
with this command line option.

command line to reproduce:
setenv CLASSPATH ./jbb.jar:./jbb_no_precompile.jar:./check.jar:./reporter.jar:$CLASSPATH
java -Xrunhprof:heap=dump -ms256m -mx256m spec.jbb.JBBmain -propfile SPECjbb.props
