Filtering Some Exceptions on Log4J 1.X

SDKs
1

Hello there,

I want to filter some exceptions with Log4J 1.X then i resolved my problem via adding additional library that named log4j-extras-1.2.17.jar in my project. I cannot change log4j.properties to log4j.xml or i cannot upgrade log4j 1.x to log4j 2.x due to my project framework capacities (SmartfoxServer 2X)

I can filter exceptions that contains FORCE_UPDATE and REGULAR_UPDATE on their message, but i cannot filter exceptions that contains “Room is full” on their message. I tried many combination. I wonder working principle Log4J StringMatchFilter but first, i have to find a solution my problem quickly. Do you know any filter in this library or way to filter exceptions that contains “Room is full” text? Below is my excepiton and filters.

Best regards.

My Exception is:

07 Apr 2017 | 11:45:26,499 | ERROR | SFSWorker:Ext:1 | Extensions | | EXCEPTION
