JDK 1.8 does not allow to put null values to the ConcurrentHashMap and throws NullPointerException on such occasion.

However, WSEndpointDeploymentUnit#addEndpoint passes viewName=null to the POJOEndpoint constructor. ReflectionServiceFactoryBean#setServiceProperties later tries to put that value to the map, which causes NullPointerException.

Currently this only happens on EAP 6.x with JDK 1.8. This fails to start application server with standalone-xts.xml configuration.
