Description

When compiling this interface:

@CompileStatic
interface Service {
  TypeReference<Map<String, Object>> STATE_TYPE_MAP = new TypeReference<Map<String, Object>>(){}
}

the stub generator produces code that does not compile under Java 11:

@groovy.transform.CompileStatic() public interface Service
<T> {
;
com.fasterxml.jackson.core.type.TypeReference<java.util.Map<java.lang.String, java.lang.Object>> STATE_TYPE_MAP;
static { STATE_TYPE_MAP = null; }

[ERROR] Service.java:[6,112] = expected
[ERROR] Service.java:[7,8] initializers not allowed in interfaces
