Duplicate enum names in Java output.

[NightlyNexus]

{
  "id": "message.json",
  "title": "message",
  "description" : "Schema definition of message",
  "$schema": "http://json-schema.org/schema#",
  "type": "object",
  "properties": {
    "text" : { "type": "string" },
    "foo" : {
      "type" : "string",
      "enum": [
        { "default" : "none", "description" : "none" },
        { "default" : "foo1", "description" : "foo1" },
        { "default" : "foo2", "description" : "foo2" }
      ],
      "default" : "none"
    },
    "bar" : {
      "type": "string",
      "enum": [
        { "default" : "none", "description" : "none" },
        { "default" : "bar1", "description" : "bar1" },
        { "default" : "bar2", "description" : "bar2" },
      ],
      "default" : "none"
    }
  },
  "required": []
}

generates

public abstract class Message {
  public static final String NONE = "none";
  public static final String BAR1 = "bar1";
  public static final String BAR2 = "bar2";
  @StringDef({NONE, BAR1, BAR2})
  @Retention(RetentionPolicy.SOURCE)
  public @interface MessageBar {}
  public static final String NONE = "none";
  public static final String FOO1 = "foo1";
  public static final String FOO2 = "foo2";
  @StringDef({NONE, FOO1, FOO2})
  @Retention(RetentionPolicy.SOURCE)
  public @interface MessageFoo {}
  ...
}

This is illegal because NONE is defined twice in the Message class.

It'd be nice to generate qualified names like the following.

@StringDef({NONE, BAR1, BAR2})
@Retention(SOURCE)
public @interface MessageBar {
  String NONE = "none";
  String BAR1 = "bar1";
  String BAR2 = "bar2";
}
