In a scenario where there are multiple SY modules packaged inside an EAR and one or more of the SY module is a WAR, the application fails to deploy if the SY enabled interfaces reside in WAR. The SY application deployer tries to deploy SY components inside the war module using the ear classloader but unlike other types of ear sub-modules the war module classloader is always isolated (as per specifications). That is why the jar sub modules are deploying fine but not the war.
The sample application to replicate the problem is attached.
