Surprising behavior casting BigInteger to int/long for constructor call

[Sean Gilligan]

When I try the following code (on either Groovy 3.0.9 or Groovy 4.0.0-rc-2)
class I {
    long v;

    I(int i) {
        v = i;
    }
}

class L {
    long v;

    L(long l) {
        v = l;
    }
}

def a = new I(1G)
def b = new L(1G)

I get `Could not find matching constructor for: L(BigInteger)` when 
trying to construct an `L`.  The `I` is constructed without error.

Am I missing something or is this a bug?
