Unpack200 alternatives

It is Apache Netbeans which is on the list.

The IDE/Platform is updated/updating to newer Java it’s how to handle the legacy plug-ins that I’m concerned about

Its the independent plugins which leverages pack 200 / unpack during plug-in install.

Presently there is issue (1) in work for this but it didn’t seem clear to me at first why it didn’t handle the use case of unpacking existing pack200 in a newer JDK environment but I’m guessing one of the pack200 forks may be the way forward.

Is your "massive project" listed at
https://wiki.openjdk.java.net/display/quality/Quality+Outreach ?

Can you share some of the problems migrating from JDK N to JDK N+1? We
understand that JDK 8 to 9 (or straight to 11) can be tough, but
migrating from JDK 15 to 16 should be straightforward.
