The suggestion was made to move it into META-INF/version/9 so it would be ignored - which did help with some tools but not others. For example, I think Android still has not been fixed.

There was a thread on core-libs-dev in Dec 2017 with subject line 
"Android and Log4j". I see Martin Buchholz replied to say that the 
issues with the Android tools were fixed:

In the thread I see Uwe Schindler suggested moving the module-info.class 
META-INF/versions/9 but I don't think it was established if that worked 
around the limitations of the tools or not. One of the linked issues in 
the discussion suggests these tools weren't unpdaetd to ignore class 
files in META-INF until recently:
