Hello,

I am trying to build objenesis 2.5 on Debian Unstable but I get the following test failure now while 2.4 was working fine. I am using OpenJDK 8 but this issue is also reproducible with OpenJDK 7 and Oracle Java 8. However the test works fine on Windows 7 with Java 8. Someone else confirmed to me that he sometimes experiences a different error in the same class. Relevant output below:
