[jira] Commented: (MNG-1178) weird junit classloader issue
[ http://jira.codehaus.org/browse/MNG-1178?page=comments#action_65570 ]
David Boden commented on MNG-1178:
----------------------------------
I've been seeing this problem. After reading through this comment, I've simply changed my junit dependency from 3.7 to 3.8.1. My build now works fine. Looks like an issue with this old version of junit and is probably therefore not worth looking at as a Maven bug. Thanks.

> In some cases (that I've not narrowed down), I get this exception when doing m2 install. The affected projects have no test cases and no dependencies taht use JUnit in any way. i can get rid of this exceptino if Junit is added as a test scope dependency. It smells like a class loader issue where something funkey is going on to make the no-args constructor of UnitTest unavailable for chaining from BatteryAssert. Beats me.
