Tamás Cservenák commented on SUREFIRE-754:
------------------------------------------
Just to confirm (in practice), this fix does work great!
We had an internal build suffering from this exact problem, and to fix it, I
"back-ported" this one change and applied it to 2.9 tag of Surefire. It does
work.

Patched surefire available from here (note: version is set as 2.9-SONATYPE to
clearly mark it's patched nature)
