Answer 1

We found out the reason of such errors in our code. We were getting these errors as security realms were null in the beginning, and hence we used to get this error only once at the time of starting up application. so once after we set com.ibm.ws.webcontainer.suppressLoggingServiceRuntimeExcep property to true, we did not get similar error anymore.
