Apache tomcat printing random nullpointers

Question

Our apache tomcat server is printing random nullpointer exceptions. Normally you would see a stacktrace..

INFO   | jvm 1    | srvmain | 2012/03/30 13:44:43.733 | SEVERE: Servlet.service() for servlet frontend threw exception 
INFO   | jvm 1    | srvmain | 2012/03/30 13:44:43.733 | java.lang.NullPointerException
INFO   | jvm 1    | srvmain | 2012/03/30 13:44:46.139 | Mar 30, 2012 1:44:46 PM org.apache.catalina.core.StandardWrapperValve invoke

Can you please increase log level to debug and re-post detailed log? — rkosegi, Mar 30 '12 at 12:08
This is very generic error, so until you provide more info, I'm not able to help — rkosegi, Mar 30 '12 at 13:10

You are going to have to restart the server if you want complete stack traces. You need to set the following JVM option:
XX:-OmitStackTraceInFastThrow
