The NullPointerException looks like a bug in the logging library.

Thanks for the update.

Below is the scenario, Both the tomcat version are same.

We have two servers server1 and server2 and in each server there are two Application App1 and App2.
We are able to get logs from both applicatin logs of Server1. But for server2 we are not able to get logs from Application2.


Can you please help with this, same library is working on first server.

Or is there any other way to get logs to graylog server.
