I went to Parc 55 Mission to see Jitendra Kotamraju's (Oracle) presentation "JSR 353: Java API for JSON Processing." Kotamraju is the JSR 353 specification lead, so it's safe to assume he knows something about this "JSON for Java" JSR.

My second session on Tuesday was my first non-keynote session at JavaOne 2012 outside of the Hilton. Peter Hausel (Typesafe) gave the presentation "Modern Web Development with Play Framework 2.0" was held at Cyril Magon I in Parc 55.
