mockit.internal.ClassFile$NotFoundException

[evdzhan]

Hi there,

I am facing the following error when I try to mock an abstract class with JMockit 1.12. With JMockit 1.11 it works fine.

Enviroment :
OS Win7 64 bit
JDK 1.7.0_51 32 bit
JMockit 1.12

mockit.internal.ClassFile$NotFoundException: Unable to find class file for my.package.$Subclass_BaseWindow

The mockUp instantiation looks like :

new MockUp < BaseWindow > () {
// override stuff here
};

Here is the entire stack trace

How would I reproduce that exception? Can you show an example test?

[evdzhan]

The thing is I cannot recreate the failure in a sample case. I was hoping on you giving me an advice on when one would get this problem so I can fix it. Do you think this could be JMockit bug or rather my own code issue ?

[rliesenfeld]

I don't know.

I found a way to reproduce this bug. Maybe I can send you a maven project that exposed this bug ?

[rliesenfeld]

Yes, paste the source files here if possible, or attach a zip file to a message in the JMockit Users group (https://groups.google.com/forum/#!forum/jmockit-users).

Thanks, the sample test does reproduce the problem.

Did you see the other bug that happens with 1.11 ?
