Using pack200 to compress 1.4.2 jar

I have jars that are compiled with 1.4.2 flags, but I would like to compress the jars using the pack200 utility that comes with 1.5. Empirically, this seems to work fine. Has anyone run into any issues doing this?Thanks.

there should be no problem using pack200 with jar files contains classes compiled with the " -source 1.4 -target 1.4 " directives./Andy
