Was testing JBP 2.6 Bundled (apparently can't get a full DB on the Unix box I'll be working on) and found that the scripts in the bin/ directory didn't have execute permission (thought 2.4 did).
Not a big deal, but a heads up if you have a couple seconds to run a quick chmod before your next code commit.

File access right were lost during the packaging of sources, it's fized in SVN and should be just fine for 2.6.1
