The CI builds are broken since the Pax URL upgrade from 1.4.0.RC1 to 1.4.0:
This seems to be due to a JDK bug, I remember a similar issue from Pax Wicket.
I can reproduce the issue locally compiling the 2.4.0 sources with JDK 1.6.0_26 (Linux 64 bit).
After downgrading the Pax URL dependency to 1.4.0.RC1, the problem disappears.
With 1.6.0_32 or 1.7.0_04, everything is fine.
So I think we should upgrade the JDK on the CI server.
new 1.6.0_32 is default
Just had a look at the Hudson config pages: I don't see a JDK 6, and JDK 7 is the default.
Pax Exam is fine with JDK 7, but I don't think that's what you intended, or is it?
