John Wagenleitner commented on GROOVY-7701:
-------------------------------------------
A workaround would be to use
{code}
subClass.with {
delegate.type = ['String']
}
{code}
It only seems to be a problem if the name is the same but the types are
incompatible. If TopClass.type type is String it works correctly (only the
SubClass.type is set).

> Project: Groovy
> Issue Type: Bug
> Components: groovy-jdk
> Affects Versions: 2.4.3, 2.4.4, 2.4.5
> Environment: all?
> Tested with Ubuntu 14.04.3 LTS (64 Bit) | MacOS 10.11 and Groovy 2.4.5, 2.3.4
> Reporter: Maik Igloffstein

> h1. Problem
> {code}
> subClass.with {
> type = ['String']
> }
> {code}
> Should change _SubClass.type_ and not _TopClass.type_.
> The script works fine with _type2_ instead of _type_. Is _type_ a reserved
> word? I can't find any documentation about this.
