Gary D. Gregory commented on LOG4J2-3205:
-----------------------------------------
You MUST use Java 8 to target Java 8 in this case because Java changed some
definitions from version 8 to 9. You will also need Java 9 or 11 in your Maven
toolchain file.

> Using mvn with jdk9, the compiled sources would throw NoSuchMethodError
> ByteBuffer.clear when running in a jdk1.8 env.
> if change the pom.xml, using
> <maven.compiler.release>8</maven.compiler.release> instead of the orginal
> maven.compiler.source and maven.compiler.target,it would solve the problem.
