Christian Mouttet commented on MNG-1178:
----------------------------------------
Brett,
to reproduce the bug you can write a simple TestCase like this (initializing
Log4J):
public class SimpleTest extends TestCase {
static {
URL url = AbstractTestCase.class.getResource("/test-log4j.xml");
DOMConfigurator.configure(url);
}
// any tests you like to do ...
}
I have maven-2.0 with surefire-1.4 and junit-3.8.1.

> 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.
