Suboptimal expression in javax.imageio.ImageTypeSpecifier.getBitsPerBand(int)

The code uses non-short-circuit logic (|) rather than short-circuit logic (||). Non-short-circuit logic causes both sides of the expression to be evaluated even when the result can be inferred from knowing the left-hand side.
