----------------------------------
Summary: Inherting the same Generic Interface at different levels
in an inheritance hierachy causes error
Key: GROOVY-11707
URL: https://issues.apache.org/jira/browse/GROOVY-11707
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 5.0.0-beta-1
Reporter: Saravanan
{code:java}
public class Testing {
interface TopLevel extends Comparable {
void blah();
}
interface NextLevel extends TopLevel, Comparable {
}
} {code}
Compiling this with @CompileStatic enabled results in this error
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
testdata/plugins/records/RecordTesting.java: 10: The interface Comparable
cannot be implemented more than once with different arguments:
java.lang.Comparable<java.lang.Object> and java.lang.Comparable
. At [10:5] @ line 10, column 5.
interface NextLevel extends TopLevel, Comparable {
^ {code}
Not sure if this is expected behaviour. The error goes away if I extend
Comparable<Object>
