[fedora-java] Unexpected Exception on JVM shutdown

[Krzysztof Daniel]

Hey everyone,

I've recently switched to the f20, and each time I shutdown Eclipse,
ABRT reports an error (via abrt-java-connector):

Uncaught java.lang.ClassNotFoundException exception in thread "main" in
a method java.lang.ClassLoader.loadClass() with signature
(Ljava/lang/String;Z
)Ljava/lang/Class;
Exception in thread "main"

This stack trace is beyond my skills. It looks like JVM tried to
interpret a jar as a class, but since VM is going down, I get no chance
to debug it (jvm is terminated before remote breakpoint is even hit). 
As I have no clue what to do with it further, I'd appreciate any advice.
