Thodoris Sotiropoulos updated GROOVY-10228:
---
Description:
I think this bug is related to GROOVY-9963.
I have the following program
{code:java}
class A {
T x; A(T x) {
this.x = x;
}
T getX() {
return x;
}
}
class B {}
class Main {
public static void m1() {
def x = new B();
m2(new A<>(x).getX());
} public static void m2(B x) {}
}
{code}
h3. Actual behaviour
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 18: [Static type checking] - Cannot find matching method
Main#m2(T). Please check if the declared type is correct and if the method
exists.
@ line 18, column 5.
m2(new A<>(x).getX());
^1 error
{code}
h3. Expected behaviour
Compile successfully
Tested against master.
