Invalid code generation when using collections of generated types

[bm-w]

Take for example this (partial) schema, where the root type has a field that’s a list of element of another generated type:

{ …, "types": [
  {
    "name": "Root",
    "description": "The table’s root type",
    "fields": [
      { "name": "id", "dynamoName": "id", "description": "The hash key", "type": "String" },
      { "name": "listOfGenerated", "dynamoName": "logen", "type": "List", "elementType": "GeneratedListElement" }
    ]
  },
  {
    "name": "GeneratedListElement",
    "fields": [
      { "name": "foo", "dynamoName": "foo", "type": "String" }
    ]
  }
] }

The generated RootBean class will have the following annotated member variable, where the argument to the annotation contains invalid syntax:

@JsonDeserialize(as=List<GeneratedListElement>Bean.class)
private List< GeneratedListElement> listOfGenerated;

This invalid code is generated by line 42 of bean.ftl (as of current master, 952ed0e):

@JsonDeserialize(as=<@field_type field=field />Bean.class)
