rpmlint problem: Class-Path in manifest problem

[Igor Foox]

Hi,

I'm building the following src.rpm:
http://people.redhat.com/ifoox/extras/ant-contrib-1.0-0.1.b2.src.rpm

and I get this error from rpmlint:
W: ant-contrib
class-path-in-manifest /usr/share/java/ant-contrib-1.0.jar

Does anybody know what this mean, and why it's considered bad?

The manifest file contains this line, which is the culprit:
Class-Path: ant-contrib.jar

Thanks,
Igor
