Daniel Sun commented on GROOVY-5318:
------------------------------------
the new parser Parrot can parse the following code:
{{def a= new java.util.ArrayList<ArrayList<Integer>>()}}
Generics for package? Groovy does not support the syntax...
{{java.util<Integer>}}
> generic types in fully-qualified class names parsing error
> ----------------------------------------------------------

> Key: GROOVY-5318
> URL: https://issues.apache.org/jira/browse/GROOVY-5318
> Project: Groovy
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.8.6
> Environment: Groovy 1.8.6 on Java 7
> Reporter: Gavin Grover
> Priority: Minor
> Fix For: 4.0
>
>
> The following code compiles and runs in Groovy 1.8.6...
> {code}
> def a= new java.util<Integer>.ArrayList<ArrayList<Integer>>()
> {code}
> The parser allows a generic type after each name in the fully-qualified class
> name. The generic type should only be after the final name.
> The relevant part of the Antlr parser that needs fixing is:
> {code}
> typeParameters: LT typeParameter (COMMA typeParameter)*
> (typeArgumentsOrParametersEnd)?
> typeParameter: IDENT (typeParameterBounds)?
> typeParameterBounds: "extends" classOrInterfaceType (BAND!
> classOrInterfaceType)*
> {code}
