Description

@Delegate seems to breaking the use of generics a bit.

This script goes through:

GroovyClassLoader gcl = new GroovyClassLoader()

gcl.parseClass """
    class A {
        List a
    }
"""

gcl.parseClass """
    class B {
        List<String> a
    }
"""

This script fails:

GroovyClassLoader gcl = new GroovyClassLoader()

gcl.parseClass """
    class A {
        @Delegate List a // use of @Delegate List affects use of List<String> later
    }
"""

gcl.parseClass """
    class B {
        List<String> a
    }
"""

with the error

script1253728549265.groovy: 3: The class java.util.List refers to the class java.util.List and uses 1 parameters, but the referred class takes no parameters

It seem to be happening because DelegateASTTransformation#nonGeneric(ClassNode) seems to be clearing the generics information from the ClassNodes statically loaded by org.codehaus.groovy.ast.ClassHelper
