[cbi-dev] Maven 3.1.0, Java 7, and Hudson?

[David M Williams <david_williams@xxxxxxxxxx>]

I think I've heard of "issues"
before ... but don't recall enough details to know where to look, so thought
I'd ask here ... 

I'm trying to change one of our small
Hudson utility builds to use Maven 3.1.0, and Java 7 "latest",
but get an unusual error that seems to say something is incompatible, perhaps
with the way slaves are setup? The trouble starts with some "class
not found" errors .... and gets worse from there ....

Do I just have something configured wrong, or are there known issues? Are there work-a-rounds?
