Not right now... The ClassCastException occurs deeply inside Storm. I guess it is a Storm issue.
I just instantiate a (Storm)LocalCluster and it fails internally. > LocalCluster cluster = new LocalCluster(); Maybe I need to try it locally with Java 8 JDK to be able to debug it... I will pick up this thread again if I have more information. As a fall back, we might want to deactivate this test for Java 8 (if this is possible). -Matthias On 09/16/2015 12:34 PM, Stephan Ewen wrote: > Do you know between what classes the exception is?
