Test failure: org.objenesis.instantiator.basic.ClassDefinitionUtilsTest

[apoleon]

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:

Indeed. I can reproduce. Let me investigate.

It seems to be an obscure JDK bug. I've workaround it. Do you need a new release?

Hey, thank you very much for your quick response. I wouldn't mind if you made a new release. If this is a burden for you, I could also apply your patch because Debian is approaching the "freeze" very quickly. After next week I won't be able to package a newer release of Objenesis for the next stable release aka Stretch. I could either wait for your next release until then or apply the patch to get the latest release of Objenesis into Debian Stretch. Of course 2.4 is working fine at the moment, so there is no compelling reason for an update at the moment. But if you rather want to see 2.5 in Debian stable, please let me know.

I will try for a release tonight. Debian users should get the shiniest version of Objenesis ;-) Thanks.

Thank you very much. I have uploaded 2.5.1 to Debian unstable a few hours ago. Regards, Markus
