have you tried to use org.alfresco.repo.policy.JavaBehaviour.NotificationFrequency.TRANSACTION_COMMIT instead of org.alfresco.repo.policy.JavaBehaviour.NotificationFrequency.EVERY_EVENT

Yes earlier I did that was not able to create user from UI. So changed to EVERY_EVENT.

I think maybe you should execute your code atfer the transaction event commit

You can refer to https://joinup.ec.europa.eu/svn/circabc/SDK%20Circa/source/java/eu/cec/digit/circabc/aspect/ContentNotifyAspect.java
