[2.0.6] LinkageError with Maven 2.0.6

Wed, 11 Apr 2007 11:35:29 -0700 

Hi
In Apache FtpServer we have had two users independently [1}[2] run into a problem where Surefire fails a test due to a class loader issue. I can reproduce the error on my laptop by simple upgrading from 2.0.5 to 2.0.6. On 2.0.5 it works as expected. The version of maven-surefire-plugin used is 2.0 due to another problem reported with 2.3 [3]. Seems like 2.3.1 has not yet been released. 

Any clue to why this happens?

The stack trace is provided below.

Thanks!
