Elliotte Rusty Harold updated DOXIATOOLS-67:
--------------------------------------------
    Description: 
It also has known security issues. Do we really need this in out classpath? 

A security vulnerability, CVE-2019-17571 has been identified against Log4j 1. 
Log4j includes a SocketServer that accepts serialized log events and 
deserializes them without verifying whether the objects are allowed or not. 
This can provide an attack vector that can be expoited. Since Log4j 1 is no 
longer maintained this issue will not be fixed. Users are urged to upgrade to 
Log4j 2.
