Paul King closed GROOVY-5358.
-----------------------------
> Different ways of extending a class functionality esp. adding getProperty
> inconsistent
> --------------------------------------------------------------------------------------
>
> Key: GROOVY-5358
> URL: https://issues.apache.org/jira/browse/GROOVY-5358
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime

> Assignee: Eric Milles
> Priority: Minor
> Fix For: 4.0.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h

> When getProperty is used e.g., to mimic a Map behaviour, the result differs
> depending on whether getProperty was defined directly in the class, added
> through a mixin, or through a metaclass.
> {code}
> class FooWorksAsMap { // class names the same length as LinkedHashMap to make
> output pretty
> def getProperty(String foo) { "OK:FooWorksAsMap.$foo" }
> }
> class BarWorksAsMap {}
> class BaxWorksAsMap {}
> @Category(BarWorksAsMap) class C {
> def getProperty(String foo) { "OK:BarWorksAsMap.$foo" }
> }
> BarWorksAsMap.mixin C
> BaxWorksAsMap.metaClass.getProperty = { foo -> "OK:BaxWorksAsMap.$foo" }
> def maps = [new FooWorksAsMap(), new BarWorksAsMap(), new BaxWorksAsMap(),
> [foo:'OK:LinkedHashMap.foo', class:'OK:LinkedHashMap.class']]
> for (def prop in ['foo','class']) {
> for (def m in maps) {
> def op = "${m.getClass().getSimpleName()}.$prop"
> try { println "$op -> " + m."$prop" }
> catch (t) { println "$op -> FAIL:$t" }
> }
> }
