-------------------------------------------------------------
That does look wrong but unrelated. It matches what this gives:
{code}
Integer x = -1 & 3
{code}
but this is okay:
{code}
Integer x = 1 & 3
{code}
and this is okay:
{code}
int a = -1
int b = 3
int c = a & b
{code}
It seems that we match on {{NumberMathModificationInfo#or}} for primitives but
fall back to the {{Number}} variant for wrapper types. And for whatever reason,
constant 3 is given type {{int}} but constant -1 is given type {{Integer}}. We
don't do that for other operators like + and *, so there is room for
improvement there.

> Affects Versions: 2.4.13
> Environment: any
> Reporter: Patric Bechtel
> Priority: Critical

> This used to work up to 2.4.12:
> {code}
> @groovy.transform.CompileStatic
> class bla {
> static void main(String[] args) {
> println new Long( 5 / 3 )
> }
> }
> {code}
> starting with 2.4.13, it gives this error message:
> {noformat}
> bla.groovy: 4: [Static type checking] - Cannot find matching method
> java.lang.Long#<init>(java.math.BigDecimal). Please check if the declared
> type is right and if the method exists.
> @ line 4, column 15.
> println new Long( 5 / 3 )
> {noformat}
