>            Reporter: Raymond Chee

> This small thrift file fails to compile.
> {code:java}
> enum SomeEnum {
>     A,
>     B,
>     C
> }
> typedef map<SomeEnum, i32> SomeMap
> const SomeMap MY_MAP = {
>     SomeEnum.A: 123,
>     SomeEnum.B: 456,
>     SomeEnum.C: 789
> }
>  {code}
> Trying to compile this thrift file results in this error: 
> {code:java}
> [FAILURE:generation:1] Error: have identifier "SomeEnum.A", but unset enum on line!{code}
>  
> If I didn't use the typedef and instead declared MY_MAP with type map<SomeEnum, i32>, there is no issues with compilation. This issue also happens if SomeEnum is the value type in the map, and it also happens for typedefs of lists of enums.
