Your faithful Java To Go blogger won’t be able to make it to JavaOne next week, which is too bad, because I’d love to gauge the mood of developers on the floor. Presumably the feeling will mainly be of uncertainty: the Sun-Oracle merger won’t have closed yet, so there still won’t be any definitive guidance on what Oracle-owned Java will look like. In fact, InfoWorld’s Paul Krill speculates that this might be the last JavaOne ever, with things being rolled into the Oracle OpenWorld conference. He cites as evidence the fact that there’s no JavaOne conference on the Moscone Center’s calendar for 2010.It seems unlikely to me that Oracle would actually just kill the conference entirely so quickly, not least because (so I’ve heard) it’s actually a fairly tidy little money-maker (and oh if there were more things with “Java” in the name about which that could be said). But it’s certain that this year’s conference will definitely have a “last party” feel to it. Big ticket events to happen there? SpringSource will be promoting its “industry leadership” (i.e. vast Java-ruling ambitions) at a number of events promoting version 3.0 of the Spring Framework; Microsoft will be making its first ever JavaOne appearance, claiming that it totally loves Java now and that you can even integrate it with .Net; and, of course, Sun will unveil the detail of the Java Store, which we’ll all be interested to see, even if only to figure out how another possibly promising initiative can be botched.
