Trying to login to jira, getting null pointer exception

[Matthias Kunka]

Our JIRA-Software runs with postgresql DB, version 9.4. The Databse-Server runs in a virtual Debian-machine (Hyper-V) which is installed on our domain contoller (Windows Server 2012 R2). Also JIRA is installed on the DC.  Everything worked well, but after our DC received new windows updates the JIRA Login fails. The VM and postgresql are running. If someone tries to Login then an error message appers in the browser-window:

JIRA — Internal Server Error

Error reference: 44a95f7d-79b9-437a-acb9-260d73e85eed

How can I resolve this problem?

Is there more of your log?

My guess is that your server update broke either a path or added some security checking that breaks it, but it's impossible to tell from that snippet of log.

It's already solved. The issue was caused by the reboot of our server. As the server was up JIRA is started but the virtual Debian system with the JIRA-db started some time later. I guess JIRA needs some data from the db to start up properly but there was no chance to connect because the db was not running at this time. The solution was a restart of JIRA. Thank You and sorry for eventually inconvenience.
