Simple one but can appear a bit odd.

short s = 5;
// fine the 5 is of type int but
// as it is literal is automatically narrowed to a short

myMethod(short s) {}

myMethod(5);
// not okay myMethod accepts a short
// and will not automatically narrow
// anything, even if it is literal.

& just to add:

myMethod((byte)5);
// fine, byte is narrower than short,
// this works on literals and variables
