JSON Libraries

[Danny Sullivan]

Hey,
Assuming that activitystrea.ms JSON is parsed once it has been published, is 
there a preference for a Java library for parsing that JSON? I noticed that 
dummy text is currently being inserted and returned along with a log statement 
printing the full text JSON. I was planning on playing around with parsing what 
is published, so I thought I'd get some input on what libraries to use.
Thanks,
Danny
