Hi,
I get the following NPE in the findbugs plugin. It looks like the
inner class BCELComparator in JavaClass does not compare for null
objects.
Caused by: java.lang.NullPointerException:
While finding bugs in class: ....

Oddly, I only get this exception if I run 'mvn site' from the root
module, generating the site from the culprit submodule does not
trigger this. Any ideas?
