Eric Milles closed GROOVY-8136.
-------------------------------
Resolution: Not A Bug
[MultiValueMap|https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/util/MultiValueMap.html]
is an interface, so you cannot assign a map literal (aka {{LinkedHashMap}}) to
it without some kind of explicit conversion.
> Code passes static compilation but fails during runtime
