The exception above is caused by Infinispan using (by default) invocation context's
ClassLoader when trying to read the component metadata. In a modularized environment such
as AS7 this will cause the metadata not to be found (metadata is packaged in the same jar
as the infinispan class that reads it). In order to overcome this problem we should try
to use both class' ClassLoader and InvocationContxt's class loader when trying to
read the metadata.
Workaround: set the class loader on the GlobalConfiguration object:
{code:java}
GlobalConfiguration.classLoader( GlobalConfiguration.class.getClassLoder())
{code}
