> A server task is deployed and the task generates annotation based protostream marshallers during context init.
> A NullPointerException is thrown as seen in this stacktrace, but this is another issue in javassist which obscures the real reason, a  java.lang.NoClassDefFoundError: org/infinispan/protostream/ImmutableSerializationContext.
> The NoClassDefFoundError is caused by the use of the thread context classloader in the ClassPool of javassist. The TCL is not always suitable. At least it never is for deployed server tasks.  There is no workaround for this, and the only option is to modify ProtoSchemaBuilder.build signature, or add an overloaded method that also accepts a ClassLoader so the user can take control.
