Re: [pde-build-dev] Pack200 vs jarOptimizer.

[Andrew Niefer <aniefer@xxxxxxxxxx>]

The Jar Processor will recurse and pack
nested jars while the pack200.exe doesn't.  This is the likely explanation
for the size difference you are seeing.

So whether or not unpack200 would work
on a pack.gz file made with the jar processor would depend on whether or
not there were nested jars.

The Jar processor does provide a Main
class so that it can be used without having the eclipse executable.  In
fact you can export the jar processor as a stand-alone jar separate from
update by using org.eclipse.update.core/org.eclipse.update.internal.jarprocessor/jarprocessor.jardesc.
