Motivation: We need to always return a real slice even when the requested length is 0. This is needed as otherwise we not correctly share the reference count and so may leak a buffer if the user call release() on the returned slice and expect it to decrement the reference count of the "parent" buffer. Modifications: - Always return a real slice - Add unit test for the bug. Result: No more leak possible when a user requests a slice of length 0 of a SlicedByteBuf.
