------------------------------------
Assignee: Eric Milles
> Static compilation error using generic classes with maps
> --------------------------------------------------------
>
> Key: GROOVY-10774
> URL: https://issues.apache.org/jira/browse/GROOVY-10774
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.11, 3.0.12
> Environment: Windows using Java 1.8.0_211
> Reporter: AN
> Assignee: Eric Milles
> Priority: Major
>
> I was updating an old library to use Groovy 3 and I found a static
> compilation error. The error starts occurring since Groovy 2.5.16,
> previously tested versions of 2.5.x compile successfully.
> The error can be reproduced with:
> {code:groovy}
> import groovy.transform.CompileStatic
> @CompileStatic
> class MyGenericClass<K> {
> //protected LinkedHashMap<K, String> valuesMap = new LinkedHashMap<>()
> protected Map<String, K> keysMap = new LinkedHashMap<>()
> void put(K k, String v) {
> keysMap.put(v, k)
> //valuesMap.put(k, v)
> }
> } {code}
> The error only happens when the parametrized type is used as the value of the
> map.
>
> {code}
