We will not be removing Pack200 in Java 12.

pack200 is used by the Eclipse update manager a.k.a. p2. The JARed

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.
