weird junit classloader issue
-----------------------------
Key: MNG-1178
URL: http://jira.codehaus.org/browse/MNG-1178
Project: Maven 2
Type: Bug
Environment: java 1.5, linux
Reporter: Matthew Pocock
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.
