We are now getting complaints from Android users (as well as a few others) that their tools no longer work with log4j. During development I ran into problems with OSGi. The problems seem to mostly revolve around the fact that they can’t deal with the classes for Java 9. I was surprised that Android is failing on the classes in META-INF/versions/9 as I had assumed that would be an invalid location for a class file prior to Java 9, but that seems not to be the case. The fact that module-info.java turns into a class file also seems to be a problem since the various tools are seeing it and having problems with it. : Do you have any recommendations on how we can resolve this impasse? The Android tools should ignore class files in META/**, at least until they are updated to work with multi-release JARs. Have you created a bug for them to look at this issue?

Yes, although I don’t develop for Android so I am not certain I created the issue correctly. https://issuetracker.google.com/u/1/issues/70118537 <https://issuetracker.google.com/u/1/issues/70118537>.

I also created https://issues.apache.org/jira/browse/FELIX-5592 <https://issues.apache.org/jira/browse/FELIX-5592> which relates to https://issues.apache.org/jira/browse/FELIX-5527 <https://issues.apache.org/jira/browse/FELIX-5527>. No activity has occurred on either of these issues.
