Do not check for multi-release jar when reading files from META-INF

Related to #41395

@dmlloyd my understanding is it's the classes that can be multi-releases, right?

Here, I'm trying to avoid reading the manifest when we go find the quarkus-extension metadata in the jars.

[dmlloyd]

Right, this check looks safe to me.

Just in case, the multi release concept isn't limited to classes.
See Class Loader Resources paragraph in https://openjdk.org/jeps/238 for an example.

I think in this case (META-INF) it's OK. The JEP says this:

A JAR file has a content root, which contains classes and resources, as well as a META-INF directory which contains metadata about the JAR.

And then later:

JAR metadata, such as that found in the MANIFEST.MF file and the META-INF/services directory, need not be versioned.

I would generally extrapolate this to include anything in META-INF (including the versioned directories themselves, which otherwise would lead to some ugly recursion problems).

[aloubyansky]

Agreed
