Re: [p2-dev] pack200, JRE versions requirements


thanks a lot. I have more questions:

Does that mean that the entire jar remains unpacked or perhaps
some parts of it?

It appears that this cannot be controlled for individual bundles
 but for the entire build using system property
"org.eclipse.update.jarprocessor.pack200". In Eclipse builds where is
the value set?

In one example produced using JarProcessorExecutor the eclipse.inf
file does not contain the pack200.args property:
 #Processed using Jarprocessor
 pack200.conditioned = true

There is no pack200.args property. Does this mean some defaults are
used? Are the defaults documented? In practice should every bundle
specify pack200.default.args in its eclipse.inf file?
