dariusan commented on GROOVY-8018:
----------------------------------
I see, the returned value or default in the map could be a closure. Ok then
this is not a bug.
> map with default value creates entry on MissingMethodException

> Key: GROOVY-8018
> URL: https://issues.apache.org/jira/browse/GROOVY-8018
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.5
> Reporter: dariusan
>
> Calling an inexisting method on a map with default values leads to an
> Exception and alters the content that map:
> {code}
> def map=[:].withDefault{[]}
> try{
> map.inExistingMethod()
> }catch(e){
> println e
> } finally {
> println map
> }
> {code}
> outputs the following:
> {code}
> groovy.lang.MissingMethodException: No signature of method:
> groovy.lang.MapWithDefault.inExistingMethod() is applicable for argument
> types: () values: []
> [inExistingMethod:[]]
> {code}
> where throwing an Exception is ok but not altering the content of the map
