When emerging dev-java/commons-lang-2.0-r1 with the 'junit' USE flag set, the
build failed because the junit library was not set correctly during the build


Reproducible: Always
Steps to Reproduce:
1. Set the junit USE flag
2. emerge dev-java/commons-lang-2.0-r1  (this may have been present in the
previous versions)
3. During the test phase, the build fails with the output shown below.

Actual Results:  
The ebuild failed with the following output:

There are two workarounds which I found fixed this problem, the second could be
used to fix the issue long term.

1- Remove junit USE flag prior to emerging the ebuild.

2- Perform the following after the source is unpacked and prior to compilation:
 echo junit.jar=`java-config -p junit` >build.properties

this will put the proper junit library into the variable used for setting the
classpath prior to running the test.

Created an attachment (id=31442) [details]
patch for updating ebuild to fix issue

I created this patch based on the changes to the commons-cli ebuild which
performs a similar action

Thanks, fixed in portage.
