We recently changed our build system to force you to use javac 1.5. While you can build the system with javac 1.6 (and you can certainly build apps with 1.6), many members of the Android team still need to use javac 1.5 for various reasons (mostly because Mac OS X.) If someone uses javac 1.6, we are at risk of checking in code that does not compile on javac 1.5 (use of @Override on interface methods.) This has been the cause of broken builds several times in the past. While we could simply use -target 1.5 -source 1.5 with javac 1.6, we decided to not take risk and make sure everyone uses a similar compiler. Thus the enforcement of javac 1.5.
