# @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
