             Summary: Regression in handling of properties of objects that 
implement the Map interface
                 Key: GROOVY-8256
                 URL: https://issues.apache.org/jira/browse/GROOVY-8256
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.4.12
            Reporter: Graeme Rocher


When upgrading to Groovy 2.4.12 there appears to be a regression in the 
handling of objects that implement the Map interface and also getters. I had to 
make the following changes to GORM:

https://github.com/grails/grails-data-mapping/commit/968ae39a54aea239943f74b4b5111fb106fb0bc4

The HttpHeaders headers object implements Map 
https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/http/HttpHeaders.html

In earlier Groovy versions the getContentType method was resolved when doing 
{{headers.contentType}}. In 2.4.12 the Maps {{get(..)}} method is resolved.

This is a breaking change and shouldn't be in a 2.4.x release.
