We are running xWiki on LTS-version 12.10.10. The following updates ara available:
xwiki-common/lts 13.10.3 all [upgradable from: 12.10.10]
xwiki-mysql-common/lts 13.10.3 all [upgradable from: 12.10.10]
xwiki-tomcat8-common/lts 13.10.3 all [upgradable from: 12.10.10]
xwiki-tomcat8-mysql/lts 13.10.3 all [upgradable from: 12.10.10]
Installing those updates works just fine. But when I try accessing the wiki, I get a HTTP 500 Error and a NullPointerException from java.

I already had the same problem when trying to update to 13.10.2, but I waited until 13.10.3 to ask here.
Do any of you have an idea why this is happening?
