>             Project: Groovy
>          Issue Type: Bug

> The following class fails when compiled by Groovy 2.5.6 (via Gradle). The error is:
> {noformat}
> src/main/groovy/Bug.groovy: 11: [Static type checking] - Reference to method is ambiguous. Cannot choose between [boolean java.sql.Timestamp#equals(java.sql.Timestamp), boolean java.sql.Timestamp#equals(java.lang.Object)]
>  @ line 11, column 13.
>            if (timestamp != null) {
>                ^
> {noformat}
> Class code for {{Bug.groovy}} -
> {code:java}
> import groovy.transform.TypeChecked
> import java.sql.Timestamp
> @TypeChecked
> class Bug {
>     public void bug() {
>         java.sql.Timestamp timestamp = new Timestamp(new Date().getTime());
>         if (timestamp != null) {
>         }
>     }
> }
> {code}
> Expected behavior: Groovy compiles "x != null" without reference to Java's {{equals}}.
