Paul King commented on GROOVY-8380:
-----------------------------------
Right, that's correct. Please ignore the assignment example difference between
static/dynamic above as dynamic Groovy has extra coercion going on of course.
So, to summarise, here is what used to happen:
{code}
Long wl = 1L
long pl = 1L
assert new Integer(wl & wl) > 0 // GRE when dynamic, STC incorrectly passes
assert new Long(wl & wl) > 0 //
assert new Integer(pl & pl) > 0 // GRE when dynamic, STC detects
assert new Long(pl & pl) > 0 //
assert new Long(6 & 3) == 2L //
assert new Long(-2 & 3) == 2L //
{code}
Here is what happens now:
{code}
Long wl = 1L
long pl = 1L
assert new Integer(wl & wl) > 0 // GRE, STC detects
assert new Long(wl & wl) > 0 // STC incorrectly fails
assert new Integer(pl & pl) > 0 // GRE, STC detects
assert new Long(pl & pl) > 0 //
assert new Long(6 & 3) == 2L //
assert new Long(-2 & 3) == 2L // STC incorrectly fails
{code}
Fixing the GROOVY-8325 bug has revealed another.
The type for x & y is being correctly determined for primitives
({{WideningCategories.isIntCategory}}) but fails for wrappers. 6 is given type
int, -2 is given type Integer, so it also fails.

> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> 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}
