I'm not an expert on this (Paul, Rado, Richard should help more…), but to do what
you're trying to do, I suspect there might be a need to export the .dat files somehow?
I know there's a way to export the metadata in META-INF/services.
Alternatively, you could let the Infinispan subsystem create the cache managers directly,
by configuring them in advance in the standalone.xml or similar. That's what happens
with Hibernate Core, which does not start its own cache manager, but simply looks it up
based on what's been configured by default in the standalone.xml (there's a named
cache manager for it). AFAIK.
Take this with a pinch of salt (some details are blurry). The experts on these are really
AS7 guys…

The ComponentMetadataRepo is unable to load
"infinispan-core-component-metadata.dat", which contains the
critically-important information for wiring together the internal
components of Infinispan core.
Now I think this is quite silly as locating this resource is trivial:
it's in the same jar as all the infinispan core classes:
infinispan-core-[version].jar so patching this looks like trivial:
it's using the ClassLoader configured as defaultClassLoader in
org.infinispan.factories.AbstractComponentRegistry, but really it
should just use something like
AbstractComponentRegistry.class.getClassLoader() ?
Things get a bit more tricky with extension modules, and a lot of
magic is being wrapped around this defaultClassLoader which goes
beyond my understanding so I would be glad to leave this issue to some
core Infinispan developer more familiar with the intentions here.
