Continuous builds for OpenJDK (was: Running findbugs)

On that note, has anyone set up or thought about setting up a public 
continuous builder for OpenJDK, e.g. using Hudson? This would ensure 
that the codeline is still buildable (of course), and could show test 
status, show FindBugs metrics, permit downloads of snapshot builds, etc.

One issue with Hudson is that it does not yet support the Forest 
extension in its Mercurial plugin. You can 'hg fpull -u' in your build 
script to do the update, but then the changelog will only show changes 
in the root tree, and polling will not work correctly. Probably fixable 
in the plugin; or it might just be better to set up a separate job for 
each tree, assuming these components can be built meaningfully in 
isolation (definitely true for langtools). You can also have 
"downstream" jobs, so it would be possible for a jdk job to use binary 
artifacts from the most recent successful build of a hotspot job, 
assuming the makefile supports this scenario.
