Bug in maven 2 -

[EJ Ciramella]

A colleague and I have found some strange behavior with the way
properties are expanded and how m2 works.
 
We've seen it such that if a property is undefined and you've activated
a profile that has build segments and this undefined property, maven
hangs just scanning for projects.
 
I couldn't find a similar bug in jira for this, has anyone else seen
this?
