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.
