This is the offending commit introduced in 1.7.19 which was done to fix a NullPointerException. Its force initializing rootLogger to fix a NPE in multithreaded scenarios looks like. The irony is this is the commit which is causing NullPointerException for us [https://github.com/qos-ch/slf4j/commit/111b8e581e247b33bb2fe66bd0118399e0b49a90] Here is the stack trace for my error:
