The "Tools in Action" talk about Scimpi was quite nice showing that it is possible to generate a web UI based on Naked Objects, but perhaps it should use more of the new JEE stuff, since all the major things are/can be now POJOs in JEE. The "Next Generation Performance Tools" talk showed the actual state of what is possible in inspecting the JVM, but only some minor(?) improvements for the new version of the JRockit toolchain.
From the BOF'S the talk from Kess Jan Koster was a real highlight. It was interesting discussing about the "Java Tuning Puzzlers" and his real good presentation style made this talk fun even though it was the 21:00-22:00 timeslot. There is one more talk with him this week - so it could be probably a good idea to go there as well, although that may be a bit more about selling and advertising java-monitoring.com. Oh and I nearly forgot - the DreamTeam once again helped out - this time with a power adapter for his Mac.
