# @summary exercise HotSpot error handling code
# @author John Coomes
# @run shell vmerrors.sh
# Repeatedly invoke java with a command-line option that causes HotSpot to
# produce an error report and terminate just after initialization. Each
# invocation is identified by a small integer, <n>, which provokes a different
# error (assertion failure, guarantee failure, fatal error, etc.). The output
# from stdout/stderr is written to <n>.out and the hs_err_pidXXX.log file is
# renamed to <n>.log.
#
# The automated checking done by this script is minimal. When updating the
# fatal error handler it is more useful to run it manually or to use the -retain
# option with the jtreg so that test directories are not removed automatically.
# To run stand-alone:
#
# TESTJAVA=/java/home/dir
# TESTVMOPTS=...
# export TESTJAVA TESTVMOPTS
# sh test/runtime/6888954/vmerrors.sh
ulimit -c 0 # no core files
