---------------------------------------

             Summary: assignment in map by named index causes casting error
                 Key: GROOVY-9069
                 URL: https://issues.apache.org/jira/browse/GROOVY-9069
             Project: Groovy
          Issue Type: Bug
          Components: groovy-runtime
    Affects Versions: 2.5.6
         Environment: Linux Mint 19.1
            Reporter: Ryan Vanderwerf


If I assign a value to a collection via a named index (key name) I get a casting error like so:

Failed to convert property value of type 'java.util.LinkedHashMap' to required type 'java.util.Map' for property 'methodConfigNames'

Here is the code in question. This doesn't happen in Groovy 2.4.15. Because Grails 4 is running 2.5.6, many plugins are failing with this error.

void setMethodConfigNames(Map<String, Map<String, List<String>>> methodConfigNames) {
 methodConfigNames.each { String key, Map<String, List<String>> value ->

 Map<String, List<ConfigAttribute>> configs = [:]

 populateMap configs, value
 methodConfigs[key] = configs  // fails
 //methodConfigs.put(key,configs) // works
 }
}

If this could get resolved it would save a lot of plugins from having to be re-released with the workaround making less confusion about the error. In some cases this works and some it doesn't. Even though I have @CompileStatic set, the issue happens at runtime.
