Hi,

Probably it can be related with JBoss Classloader, sometimes when you have a few modules A and B, both of them have for example jar file in the dependencies (not extracted into a module) you can have the problems with using the classes from this jar file in the module A and B.

What I would like to suggest that it's double check your modules that contain org/infinispan/persistence/spi/AdvancedCacheLoader and  org/infinispan/persistence/jpa/JpaStore (when they are 2 different modules) a reference to separated module that contains org/reactivestreams/Publisher class.

Thnaks,

Vlad
