Hi Seisei,
Thank you for pointing this out.
This is a know bug of type resolver since it was enhanced to support Java
types.
I filed it as the following defect.
https://jira.codehaus.org/browse/XTENLANG-3388
In the meantime, please use fully qualified name and avoid importing Java
types as a work around.
Sorry for inconvenience and thank you for cooperation.
