Version 11370 is "Bump version to 15.4". Thanks. Although ... if you generate something that is marked "Application (PPC)", then Lion users will not be able to run it, since Rosetta has been removed in Lion. Not that Rosetta is needed to execute a .jar file, but if the .app is marked PPC, I bet OS X will refuse to open it.
Considering that the .jar is architecture independent it seems silly that the .app is marked "Intel". There must be a jarbundler option to let you specify that. Hmm.
