James Daugherty updated GROOVY-11832:
-------------------------------------
Description:
I have been working on upgrading a Spring Boot Batch project that uses groovy
and found an issue in Groovy where the wrong method is invoked if the code is
annotated with CompileStatic.
The class has 2 forms of a `listener` method - one that takes a specific type
and one that takes Object. The specific type method is on the grand parent
class while the object method is on the lowest class (overrides a similar
method that is also on the grand parent class). When `@CompileStatic` is
added, the wrong method is invoked (object is called instead of the specific
type method).
Casting doesn't seem to make a difference on the method invoked. I was not
able to reproduce this with a simple example, it seems to require some
combination of generics & inheritance to trigger this.
Test project is here: [https://github.com/jdaugherty/groovy-issue-wrong-method]
Run the test `WrongResolutionSpec` to verify this behavior.
