> Key: FELIX-6344
> URL: https://issues.apache.org/jira/browse/FELIX-6344
> Project: Felix
> Issue Type: Bug
> Components: Health Checks
> Affects Versions: healthcheck.core 2.0.8
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Major
> Fix For: healthcheck.core 2.0.10
>
>
> We had this exception happening on a system every few seconds:
> [https://gist.github.com/cschneider/2840339f86faf5a46d2a8a94f0617e76]
> The root cause was an error in class loading which resulted in the
> DsComponentsCheck running into a java Error.
> The problem then was that the finish method in the FutureTask was never
> called and so the future always stayed in the list of futures to check and
> always returned the Error again.
>
> I supected that we simply should catch Throwable in the code below:
