When updating Java on OSX you may run into issues with Flash Builder afterwards. One of the issues that always forget is to update your Java Preferences ensuring that 32-bit runtimes preferred first for Java applications.

Ran into an issue today where when trying to upgrade and AIR project to Flex 3.3 I kept getting this error:

Luckily the fix is pretty simple. Download the fixlinks.sh script from the link. Copy it to your 3.3 SDK root, make it an executable and run it. You should now be able to run your AIR application with Flex 3.3.
