Hi, I have checked out latest code from log4j release-2.x branch. While trying to run ‘mvn clean install’, few unit tests in log4j-core are failing with below error

The port 8199 (used by unit test) is not in use. atulpendse@Atuls-MacBook-Pro logging-log4j2 % sudo netstat -nlat | grep 8199 atulpendse@Atuls-MacBook-Pro logging-log4j2 % Exactly same code builds without any issue on my CentOS 7 machine. Has anyone come across such an issue, or know how to work around it? Thanks for help. Thanks, Atul
