Hi All, I have a Tapestry 5.2.6 Application in production running on Tomcat 7. In general everything is running smoothly but from time to time I get the exception below. I did not get any user complain related to it, so I can't really attached it to any specific operation a user does. I did not see this exception in dev or in any of my automated testing. I will really appreciate it if some one can point me / guide me on where to start digging to find the cause.
The Exception:
java.lang.NullPointerException
