Java SE 6 u21 is Now Available

Java SE 6 update 21 is now available (Downloads, release notes, bug fixes).

This release includes performance improvements, support for Oracle Enterprise Linux, Oracle VM, and Google Chrome, and Visual VM 1.2.2. The Java EE SDK still includes u20; an update with u21 is tentatively scheduled for next week.

The actual release was a few days ago but the official post just came out. BTW, Java SE News is now at BOC; I can't wait for BSC and BOC to be merged so we only have to track one site.


Warning for those who use Eclipse...there is a serious bug using u21

what happens (I have verified this on all my projects) is that when you build any projects, you'll get a PermGen error and likely have Eclipse crash.

there is a patch available (eclipse_1308.dll, see link) that fixes the issue, but it has to be manually downloaded and installed in the correct plugins folder

Netbeans's swing visual editor hangs with JDK update 21. Looks like update 21 just buggy. Oracle fail.

I checked and it seems the JDK team is re spinning u21 to address some bugs. The JavaEE SDK refresh is waiting on that respin.
