Re: [cross-project-issues-dev] Two versions of ASM 9.3.0

I have checked this and think the asm manifest is incomplete see:

https://gitlab.ow2.org/asm/asm/-/issues/317975

This already creates trouble at xtext when there is asm 9.2 + asm 9.3 in the same framework see

https://github.com/eclipse/xtext-eclipse/issues/1842

this does not mean we have any issues in the final eclipse, but I think its crucial to check (and help) all dependencies we use to have as best osgi manifest metadata as possible, so I'd like to encourage anyone to verify the asm issue and maybe help the asm people to improve the manifest generated.

    I think there are two cases:

    1) ASM is only included transitively (e.g. there is no feature
    referencing it) and everyone uses a proper version range.
    2) It is referenced directly with a fixed version

    In the first case i think we don't have a problem as it either is not
    part of the updatesite or p2 will chose only one version

    In the second most probably two version will installed and it now
    depends how good the bundle is shaped (e.g. does it use proper
    use-clauses) if OSGi will sort that out at runtime.


ASM does not have any uses clauses in its manifest (maybe it doesn't need them) - and p2 does not use "uses" when choosing which bundles to install.

    To make the second case more lax, I have opened a bug [1] at Tycho to
    support version range inclusion of features so one do not need to stick
    to a strict version. Then it would even be possible to resolve this on
    p2 level and p2 will simply choose the highest matching version to
    install.
