[PAX-EXAM] Sporadic ServiceLookupException in JUnitProbeInvokerFactory.createProbeInvoker

[Matteo Rulli]

Hello,

We are using Pax-Exam to run integration tests based on Apache Karaf. On particularly heavy tests we experience sporadic ServiceLookupException in JUnitProbeInvokerFactory.createProbeInvoker, something like this:

org.ops4j.pax.swissbox.tracker.ServiceLookupException: gave up waiting for service org.ops4j.pax.exam.util.Injector
 at org.ops4j.pax.swissbox.tracker.ServiceLookup.getService(ServiceLookup.java:199) ~[306:org.ops4j.pax.swissbox.tracker:1.8.3]

At the time being we are solving these errors running tests twice but this is quite unsatisfactory. 

I see that the createProbeInvoker use the default 10 seconds timeout to get the Injector service. Would it be possible to apply the same approach adopted here? I would submitted a PR but I don't have access rights to create an issue on Jira.

Thank you very much,

Matteo

Hi, 

yes, it makes sense. Let me know if you want to create the PR else I will do it.

Thanks,

Regards

JB
