Subject Re: DM Lambda "stop" not being called
Date Sun, 07 Jan 2018 23:49:42 GMT
Hello Bree;

Sorry for the late response, I was on vacation.

So, your example is definitely correct, but unfortunately, you came across
a bug which I just fixed using the FELIX-5768
<https://issues.apache.org/jira/browse/FELIX-5768> jira issue.
Sorry about this silly problem, I did not see this basic issue because
there were no integration tests for it, but I just added one.

I will make a new release at the end of this week. In the meantime, if you
want, you can download the patch from here:
https://issues.apache.org/jira/secure/attachment/12905001/org.apache.felix.dependencymanager.lambda-1.1.2.jar
(you can also download it from the FELIX-5768
<https://issues.apache.org/jira/browse/FELIX-5768> jira issue).

Please replace the old org.apache.felix.dependencymanager.lambda-1.1.1.jar
bundle with the new 1.1.2 version from the above link, it should now be ok.

thanks & kind regards
Pierre
