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


I suspect it's okay, but it's definitely a bit confusing. 

I believe the eclipse/plugins/org.objectweb.asm_9.3.0.jar is present because it hasn't been garbage collected yet.  As your console indicates, only the Orbit version is resolved and the About dialog shows that too:

We see here too that the direct-from-maven bundles generally have poor provider/name information.

These are the org.objectweb.asm.* bundles in the latest 2022-06/202205061000, i.e., a bunch of duplicate 9.2.0 versions, but for 9.3.0, only the Orbit version of org.objectweb.asm along with the platform's version of org.objectweb.asm.tree.

Why are these all there in the first place? 

This view shows each duplicate org.objectweb.asm.* with nested capabilities filtered to those to which a requirement is resolved that is exclusively resolved only to that specific IU's capability.

So we can see that org.objectweb.asm.tree is present only because PDE requires it.  We can see that Xtext and Platform require the 9.3 version and while the Eclipse does not preclude a 9.4 version, Xtext's bundle requirements do exclude 9.4.  I wonder if there is a good reason for to exclude 9.4?

We can also see that ECF, EclEmma, and Linux Tools will need to take action to eliminate the 9.2 versions.  I wonder if they are paying attention?

It would seem better to me if the Platform used the Orbit versions to keep things more consistent...

OK - in that case we have some specific SimRel testing to do:

1- Which bundles ends up SimRel - or do both end up there. I assume that it will be the Orbit one because it is more recent as far as p2 is concerned (not sure, just best guess).

In 4.24 SDK there is the Maven version of asm and asm.tree.
In 2022-06 M2 p2 repo there is Maven version of asm.tree (from platform p2 repo) and Orbit version of asm (from Xtext's p2 repo)
2- Starting from the SDK, does installing features from SimRel cause both to be installed, and if so, are both resolved.

Starting with M2 SDK, installing Xtext SDK from 2022-06 M2 simrel causes asm.tree from Orbit to be installed:

osgi> ss org.objectweb.asm
"Framework is launched."

id State       Bundle
283 RESOLVED    org.objectweb.asm.tree_9.3.0
374 RESOLVED    org.objectweb.asm_9.3.0.v20220409-0157

Both versions of asm are in my plugins directory after installing xtext:

$ ll eclipse/plugins/*asm*
-rw-r--r-- 1 jonah jonah 122176 Apr 28 19:00 eclipse/plugins/org.objectweb.asm_9.3.0.jar
-rw-rw-r-- 1 jonah jonah 136049 May  5 19:57 eclipse/plugins/org.objectweb.asm_9.3.0.v20220409-0157.jar
-rw-r--r-- 1 jonah jonah  52669 Apr 28 19:00 eclipse/plugins/org.objectweb.asm.tree_9.3.0.jar

So is that OK?
