Can anybody tell what's wrong with this code?

That's indeterminate and implementation-dependent, since the two threads are unsynchronized.

The default priority of any thread is Thread.NORM_PRIORITY, which is 5. A thread inherits the priority of its parent thread. Both threads here have the same priority, but since the thread scheduler is implementation dependent, the output will be unpredictable.
