#   @summary    Test simulates the case of multiple applets executed in
#               the same VM and verifies that ImageIO shutdown hook
#               StreamCloser does not cause a leak of classloaders.

#   @run shell  run_test.sh

# There are several resources which need to be present before many
#  shell scripts can run.  Following are examples of how to check for
#  many common ones.
#
# Note that the shell used is the Korn Shell, KSH
#
# Also note, it is recommended that make files NOT be used.  Rather,
#  put the individual commands directly into this file.  That way,
#  it is possible to use command line arguments and other shell tech-
#  niques to find the compiler, etc on different systems.  For example,
#  a different path could be used depending on whether this were a
#  Solaris or Win32 machine, which is more difficult (if even possible)
#  in a make file.

#Call this from anywhere to fail the test with an error message
