[xmlvm-users] Using code from an external JDK class library for Java-to-ObjC

[Tor L. <tm...@ik...>]

A general question about the Java-to-Objective-C JDK compatibility
classes in xmlvm: Currently (and in the recent suggested patches from
Gergely Kis) they are written directly in Objective-C. I wonder
whether it would be possible to instead use suitably licensed existing
Java code, and keep just the "core" parts that acually must be so, in
Objective-C.

Obviously using stuff from OpenJDK's (i.e. Sun's, er, Oracle's) class
library is not possible or desirable because of its licensing (GPL),
but what about Apache Harmony? Is the Apache License suitable? Would
it be a good idea to just include suitable Java code from there (with
minor patches as needed) (and have xmlvm translate it into
Objective-C) instead of writing compatibility classes in Objective-C?

(Obviously, if xmlvm itself does not want to do this, nothing prevents
an xmlvm-using project to just import such code itself. But if many
projects start doing it, there will be a large amount of duplicated
work, which is a waste of precious hacker resources.)
