NBM File Creation Exception

Folks,

I was going to put up a patch today for one of our projects. When creating
the NBM files for our suite, for some reason the generator throws this
exception:

Exception in thread "main" java.lang.IllegalArgumentException: absolute
file name /
at com.sun.java.util.jar.pack.Package.fixupFileName(Package.java:881)
at com.sun.java.util.jar.pack.Package.access$100(Package.java:63)

at com.sun.java.util.jar.pack.PackerImpl.pack(PackerImpl.java:98)
at com.sun.java.util.jar.pack.Driver.main(Driver.java:313)
Result: 1

What's weird is we didn't change anything in our NetBeans code. Has anyone
run into this or have an idea of what this is telling me? For example, it
it obviously says there is an absolute file name, but how can I tell "what"
file it is complaining about?
