Plugins written for Java 9+ will fail compilation with "checking for wrong usages of ESLogger..."

ES 7.6.0:

The plugin requires Java 11; the asm library can't parse the bytecode though (even though ES itself requires Java 13).

Workaround:

// logger check does not run on jdk 11 bytecode.
loggerUsageCheck.enabled = false

As far as I can tell, this doesn't reproduce anymore and was fixed by #52742. I'm going to close, but if I'm wrong please reopen with a reproduction line.
