Hi Daniel,

I had a look at the pack200 code in openjdk, it's written in c++, and looks a little painful to maintain. I also had a look at Apache Harmony's implementation, written in Java, it uses the ASM byte code library and it's also already an OSGi Bundle. It's still only at bytecode version 1.6, but it's going to be a lot easier to maintain in the long term.

Cheers,

Peter.

pack200 is used by the Eclipse update manager a.k.a. p2. The JARed plug-ins are compressed with pack200 and put into a p2 repository. Removing pack200 will make the download (and hence install) of plug-ins much slower. Eclipse would therefore like to keep this technology. If that's not an option, then we would like that the removal does not happen before Java 13.
