Jarno Gabriel updated LOG4J2-2834:
----------------------------------
Description:
I can't seem to fix Log4j crashing when calling the `LogManager.getLogger()`
method. I found
[this|[https://stackoverflow.com/questions/52953483/logmanager-getlogger-is-unable-to-determine-class-name-on-java-11]]
thread and I included the `Multi-Release` property in the manifest file but
Log4J still crashes.
What I did was include Log4J in a library I wrote and then packaged that
library using the maven shade plugin and then I included my packaged library in
my actual application.
The error I'm getting:
{code:java}
Exception in thread "main" java.lang.UnsupportedOperationException: No class
provided, and an appropriate one cannot be found.
