snappy-java is Apache 2.0 licensed,
but it looks like it ships GPL code (contains statically linked libstdc++ governed by license [1])
which according to [2] is not license compatible.

Eclipse.org IP review found this in the context of https://bugs.eclipse.org/bugs/show_bug.cgi?id=461974
(we want to use plexus-archiver https://github.com/codehaus-plexus/plexus-archiver which in turn uses snappy-java).
Unfortunately as long as this license issue is not solved this renders plexus-archiver (and snappy-java) unusable for our purposes as governed by EPL license compatibility .
