asm is used heavily in r-OSGi and thus it might indeed have problems
with Java8. That is, why I'm reluctant to just upgrade to 5.x which
could break r-OSGi in subtle way. Thus, lets wait for this requirement
to come up (at least I don't have the resources to work on this any time
soon anyway).

Wouldn't OSGi take care of resolving 3.x and not 5.x even if both are
present in the launch config?
