Part of the problem is that OSGi Requires generator doesn't version requires (when versioned). Part of the reason is exactly because of cases like the mentioned one. Require-Bundle: org.objectweb.asm;bundle-version="[3.0.0,4.0.0)" would become Requires: osgi(org.objectweb.asm) >= 3.0.0 but that would not solve your problem either though it will definetely improve certain cases e.g. Require-Bundle: org.objectweb.asm;bundle-version="[4.0.0,6.0.0)" would properly get objectweb-asm (version 5.x) and objectweb-asm3 wouldn't be a valid solution. Definitely low hanging fruit here. Now to the non solvable part - trying to expose bundle-version="[3.0.0,4.0.0)" in rpm is impossible cause rpm doesn't support ranges and thus we should try to do it by having Requires: osgi(org.objectweb.asm) >= 3.0.0 and Requires: osgi(org.objectweb.asm) < 4.0.0 while this might work for certain cases it might also completely break the whole situation as hypothetical objectewb-asm2 and objectweb-asm6 would satisfy the RPM requirements but would be entirely useless combination from OSGi POV. This is one area where RPM lacks in my eyes - supporting ranges.
