# @test
# @bug 4262583 4418997 4795136
# @summary Check support for jar file members with sizes > 2GB
# @author Martin Buchholz
#
# @build FileBuilder
# @run shell 3GBZipFiles.sh 9986
# @ignore runs for hours and eats up 7 Gigabytes of disk space
# @run shell/timeout=604800 3GBZipFiles.sh 3141592653
# @key randomness

# Command-line usage:
# javac FileBuilder.java && sh 3GBZipFiles.sh /path/to/jdk filesize

# -------------------------------------------------------------------
# Testing strategy: We want to test for size limits on the Jar file
# itself, as well as on the compressed and uncompressed sizes of the
# files stored therein.  All of these limits should be 4GB and should
# be tested in the 2GB-4GB range.  We also want to check that it is
# possible to store more than 6GB of actual data in a zip file, if we
# have two files of size 3GB which compress nicely.  We also want to
# test both the "STORED" and "DEFLATED" compression methods.
