> Invalid reference generated in InnerClasses attribute for nested interface
> --------------------------------------------------------------------------
>
> Key: GROOVY-8614
> URL: https://issues.apache.org/jira/browse/GROOVY-8614
> Project: Groovy
> Issue Type: Bug
> Components: class generator
> Affects Versions: 2.4.15
> Reporter: Tony Abbott
> Assignee: John Wagenleitner
> Priority: Minor
> Fix For: 2.4.16, 2.5.1

> Compiling a class with a nested interface results in a reference to a
> non-existent inner class "X$Y$1" in the InnerClasses attribute of the
> resultant class file. Nested classes and inner classes do not exhibit this
> problem, only nested interfaces.
> Sample class that demonstrates the problem:
> {code:java}
> class X {
> interface Y {}
> }
> {code}
> Examining the resultant class file:
> {noformat}
> $ javap -v -cp . X.class
> ...
> SourceFile: "X.groovy"
> InnerClasses:
> public #139= #138 of #2; //Y=class X$Y of class X
> static #142= #141 of #2; //1=class X$Y$1 of class X
> {noformat}
> There is a reference to "X$Y$1" which does not exist. This breaks some tools,
> for example JUnit 5 test discovery.
>
> It looks to me like this is related to
> https://issues.apache.org/jira/browse/GROOVY-5082, being the same bug just
> manifesting for nested interfaces.
