Hello,
I am new to java ecosystem and was handed this small code which
launches a webserver. It gives a log4j version mismatch error that I
am not able to debug further.
For compilation, I am using log4j 2.12.1 version.
java.lang.ExceptionInInitializerError
application stacktrace
Caused by: java.lang.UnsupportedOperationException: Log4J2 version mismatch

io.netty.channel.MultithreadEventLoopGroup.<clinit>(MultithreadEventLoopGroup.java:35)

How do i figure out which version of log4j does netty or jvm requires.
Thank you for helping
San
