Merged on master. @bobpaulin thanks, when you have time, can you double check the IT test with JDK11? it is failing consistently on CI.

Hi @oscerd I'm able to reproduce locally on Java 11. Looks like it's something due to the removal of the JavaEE jars occurred between 8 and 11. Will need to tweak the karaf settings to make sure those Jars are available to the runtime. I'll create a JIRA for tracking this.

Looks like the issue is actually PAX-EXAM ops4j/org.ops4j.pax.exam#87 . Once this is fixed in the karaf test container startup these tests pass as expected. @jbonofre @oscerd

Thanks for the heads up :-)

@bobpaulin it works fine with Java11 if you extend KarafTestSupport. I will fix that, just at least adding the starting options for Java11: https://github.com/apache/karaf/blob/master/itests/common/src/main/java/org/apache/karaf/itests/KarafTestSupport.java#L184

I will work on OSGi part (as I think some cleanup would be welcome).
