The copyright on those images is owned by IBM.  When we re-licensed all of Jikes RVM from CPL to EPL, I guess we missed some of the meta-data.  If you can tell me how to fix the meta-information to reflect that the images are licensed under the EPL, I will do it.

For Debian, perhaps the thing to do is for you to cut these directories out of the package.

Yes. they are under the EPL.  They are generated by exporting html from our wiki.  It might be possible to figure out how to include a EPL header in them as part of the export process, but the lack of a license header in the file is not intended to be significant.

Not sure.  May depend on the package.

Jikes RVM patches the libraries and also configures their native code as part of its build process.  I would not expect Jikes RVM to work with a vanilla binary build of either GNU Classpath or Apache Harmony.  Sorry.
