It looks like they are being very strict about the scope of changes...

Presently we are aiming at removing warnings with no changes to
semantics (i.e., bytecodes).
I'll risk stating the obvious: If we have 900 warnings removals, and 30
of them remove warnings by changing code (to call a non-deprecated API
element), and 1 of those 30 introduces a bug, we have put the 900
removals at risk, because we have made it much harder for the integrator
to batch the warning changes.
So let's try to keep the deprecated call and suppress the deprecation.
(There may be an exception, of course; that's when reviews help.)
And (this is equally important) comment the @SuppressWarnings() with the
@SuppressWarnings("deprecation") // String(byte,int) in
String has been deprecated
// and this is actually useful because alskjdflsadkfjasl
String x = new String(new byte, 0);
