Gustavo Fernandes commented on ISPN-8568:
-----------------------------------------

I suppose the newly introduced AggredatedClassLoader need to somehow be passed on to the GenericJbossMarshaller. I will give it a try and send a PR

> I noticed that in this case, the Marshaller used is {{GenericJBossMarshaller}} who lives in infinispan-commons,  and when asked to de-serialize the pojo in byte[] form, the classloader  used is ModuleClassLoader for Module "org.infinispan.commons:main" that does not have visibility of the deployed jar's classes.
