Methods Summary
protected booleancheckForCompatibleServant(org.omg.CORBA.portable.ServantObject so, java.lang.Class expectedType)
Check that the servant in info (which must not be null) is an instance of the expectedType. If not, set the thread local flag and return false.

	if (so == null)
	    return false ;

	// Normally, this test will never fail.  However, if the servant
	// and the stub were loaded in different class loaders, this test
	// will fail.
	if (!expectedType.isInstance( so.servant )) {
	    isNextCallValid.set( Boolean.FALSE ) ;

	    // When servant_preinvoke returns null, the stub will
	    // recursively re-invoke itself.  Thus, the next call made from 
	    // the stub is another useLocalInvocation call.
	    return false ;
	}

	return true ;
