> MetaClassImpl triggers new entries for maps with default
> --------------------------------------------------------
>
> Key: GROOVY-6067
> URL: https://issues.apache.org/jira/browse/GROOVY-6067
> Project: Groovy
> Issue Type: Bug
> Components: groovy-jdk
> Affects Versions: 1.8.9, 2.1.2
> Reporter: Cédric Champeau
> Assignee: Pascal Schumacher
> Fix For: 2.4.6
>
>
> The following code:
> {code}
> def map = [:].withDefault { 'foo' }
> Map.metaClass.bar = { -> 'ok' }
> assert map.bar() == 'ok'
> assert !map.containsKey('bar')
> println map.keySet()
> {code}
> Fails at the second assertion, because MetaClassImpl triggers an unexpected
> get() into the map.
> Note that the behaviour is not the same if you use a per instance MC, which
> probably means inconsistencies...
