Yes that would solve the issue. The Infinispan classloader could be
used first, as it's likely the correct one for most components?

It would likely be nicer for many users than to have to use CLs in the
API - or having to figure out why Infinispan is throwing an NPE in its
own initialization - still I guess some users might want to control
the CLs being used for these purposes. Implement both?
