java.lang.VerifyError: org/primefaces/behavior/confirm/ConfirmBehaviorHandler Wrong return type in function

Question

This morning (South African time), Maven downloaded the latest primefaces jar (version 5.3). While my project is setup in a manner that maven deploys the project to my Web C

Answer 1

I had the exact same error message. The problem was that there still was the old primefaces-5.2.jar in my WAR (pulled in by Maven in my case). After cleaning the whole project the problem was gone.

So make sure that there is no older version of Primefaces hidden somewhere in your project or deployment.
