> Key: GROOVY-7763
> URL: https://issues.apache.org/jira/browse/GROOVY-7763
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.4.6
> Reporter: Graeme Rocher
> Priority: Critical
>
> After trying to upgrade Grails to Groovy 2.4.6 there are numerous problems with @CompileStatic and type inference with Maps and Lists. If I had seen the vote for the release in time I would have tested and voted -1, so sorry for only reporting this afterwards.
> This commits shows the changes I had to make in order to get Grails to compile with Groovy 2.4.6:

> You can see for example that previously returning a list initialised with variables of the correct type compiled, but no longer does:

> Also empty lists and maps no longer seem to compile. See:
