* Testcase for EJBTHREE-1868 which tests that the {@link IsLocalProxyFactoryInterceptor}
* correctly detects local invocations. The bug that was identified in EJBTHREE-1868
* showed that the {@link IsLocalProxyFactoryInterceptor} always considered the local
* calls are remote (resulting in the call going through network stack). The bug was a
* result of incorrect ordering of static fields in the {@link IsLocalProxyFactoryInterceptor}
