Description
Let the following code:
var short a = 1 as short
var short b = -1 as short
var short c = (-1) as short
The first initialization line is compiled without error.
The second initialization line generates the error "cannot cast from int to short".
The third initialization line is compiled without error.
This difference of behavior is inconsistent according to the point of view of the users of my DSL.

Start by compiling the three Xtend initializations from the issue and compare how the positive and negative literals are handled. Trace the casting or literal-processing path that produces the int-to-short diagnostic, and consider the work done when all three cases are treated consistently.
