Classpath Loader Differences between Surefire 2.3 and 2.4 causes tests to fail

[Andreas Guther]

Hi,

We see a difference in classpath loading between Surefire 2.3 and 2.4.  

If we run the attached test against Surefire 2.3 and TestNG 5.1 we get
the following output:

mvn test -Pthree

If we run the same test with Surefire 2.4 and TestNG 5.7 we get a
totally different classpath:

mvn test -Pfour

Obviously in the second case none of the dependencies or compile
directories are available.

The different behavior gives us problems with the Web Framework we use
(Stripes 1.4) and the associated tests which are not able to find any
classes under Surefire 2.4.  Stripes uses the following line to load the
classes: ClassLoader loader =
Thread.currentThread().getContextClassLoader();


Does anyone have an idea how to solve this issue and get the classes
back on the path under Surefire 2.4?

Thanks in advance for any help.

Andreas
