Native java API alternative for REST API "/rest/api/2/issue/createmeta".

[Kirankumar Gund]

Which native java APIs should I use in my JIRA  rest plugin module, so that I don't have to call the REST API "/rest/api/2/issue/createmeta" ?

I tried using FieldManager, but it doesn't gives details of the fields. e.g Allowed LOV etc.

Set<SearchableField> fieldSet1 = fieldManager.getAllSearchableFields();
