------------------------------------------------------------
Link possible cause - the idea was to make normal map semantics for put come
into play when an attempt is made to "set" a read-only property for a map - the
priority for the normal semantics path should have been lower than when a
custom set method is encountered. I am just testing a fix the re-adjusts the
priority.

> Key: GROOVY-8065
> URL: https://issues.apache.org/jira/browse/GROOVY-8065
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.8
> Environment: Java 1.8.0_102
> OS X 10.10.5
> Reporter: Andy Wilkinson
>
> There appears to be a regression in Groovy 2.4.8 that causes it to silently
> create an empty map when it's asked to create it as an instance of Spring
> Framework's {{HttpHeaders}}.
> Here's a minimal reproduction:
> {noformat}
> @Grab("org.springframework:spring-web:4.3.5.RELEASE")
> import org.springframework.http.HttpHeaders
> def headers = ['Content-Type' : 'application.json',
> 'Content-Disposition': 'test.zip'] as HttpHeaders
> println headers
> {noformat}
> It works as expected with 2.4.7:
> {noformat}
> $ sdk use groovy 2.4.7 && groovy asHttpHeaders.groovy
> Using groovy version 2.4.7 in this shell.
> [Content-Type:[application.json], Content-Disposition:[test.zip]]
> {noformat}
> With 2.4.8 the map is empty:
> {noformat}
> $ sdk use groovy 2.4.8 && groovy asHttpHeaders.groovy
> Using groovy version 2.4.8 in this shell.
