Re: [Trinidad] Nullpointer from Google Bot

Every NullPointerException is caused by a missing initialization.
My first guess is an initialization error in 
de.tccproducts.dps.web.utils.lifecycle.ExceptionFilter.doFilter

Hi List,
since our application went live, we get some nullpointer during night. Some research has shown that the IP that is accessing the site is known as some “Google Bot” scanning links, ect. Don’t know why the nullpointer happens, looks like the Google Bot sends some “strange” MacOS header in the request.
Can someone have a look at this? It’s not critical because it’s no real user, but it’s not nice to get a nullpointer every night. 

Greetings
Markus
