Do you know between what classes the exception is? What is the original
class and what the cast target class? Are they both the same, and not castable because of different copies being loaded from different classloaders, or are they really different types?

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?

Hi,
using Java 8 locally, I was able to reproduce the problem. I dug into it and could figure out the following. However, I cannot make any sense out of it. I have no experience with Java security stuff...

No clue, sorry.

Hi,
fixed it... After trying (without success) to build a minimum Java 8 example that fails (a new project extern to Flink), it was clear that JDK 8 is actually not the problem. I did some more debugging an figured out, that different class loader are used here (for the external new Java 8 and original Flink Java 8 test) > Class<? extends Configuration> implClass = Class.forName( > finalClass, false, > Thread.currentThread().getContextClassLoader() > ).asSubclass(Configuration.class); In the Flink Java 8 case, it was a "MockClassLoader". This reminded me, that I had a previous Java 7 issue, that I resolved my added a test annotation. > @PowerMockIgnore("javax.managment.*") Now I changed this to > @PowerMockIgnore("javax.*") which fixed it. The problem was, that the annotation disabled MockClassLoader for a too limited "package space" in Java 8. -Matthias On 09/16/2015 09:12 PM, Stephan Ewen wrote: > No clue, sorry. > > The Storm Mailing list may be able to help you, it looks like deep into > their code... > > On Wed, Sep 16, 2015 at 9:00 PM, Matthias J.
