# 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.+
