Hi everyone, I'm trying to manipulate json files using parser-json addon. I can save files but when I try to read them I receive a (classpath?) error: Caused by: java.lang.LinkageError: loader constraint violation: when resolving interface method "org.jboss.forge.addon.parser.json.resource.JsonResource.getJsonObject()Ljavax/json/JsonObject;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, com/github/forge/addon/music/PlaylistManager, and the class loader (instance of org/jboss/modules/ModuleClassLoader) for the method's defining class, org/jboss/forge/addon/parser/json/resource/JsonResource, have different Class objects for the type javax/json/JsonObject used in the signature at com.github.forge.addon.music.PlaylistManager.getAllPlaylists(PlaylistManager.java:178) at com.github.forge.addon.music.PlaylistManager.initPlayLists(PlaylistManager.java:57) Here is the method which throws the exception: public List<JsonObject> getAllPlaylists() { List<JsonObject> playListsObject = new ArrayList<>(); List<Resource<?>> playListsFound = getPlayListHomeDir().listResources(new ResourceFilter() { @Override public boolean accept(Resource<?> resource) { return resource instanceof FileResource && resource.getName().endsWith(".json"); } }); for (Resource<?> resource : playListsFound) { JsonResource jsonResource = resource.reify(JsonResource.class); JsonObject jsonObject = jsonResource.getJsonObject(); playListsObject.add(jsonObject); } return playListsObject; } The exception is thrown in jsonResource.getJsonObject(); The code is here: https://github.com/rmpestano/music-addon and there is a test that reproduces the error. Any help is appreciated, thanks in advance. -- <http://www.advancedit.com.br/>Att, Rafael M.

I've fixed the problem by using Json reader directly instead of using JsonResource, something like: Json.createReader(resource.getResourceInputStream()).readObject() Em seg, 12 de out de 2015 01:11, Rafael Pestano <rmpestano(a)gmail.com&gt; escreveu: > Hi everyone, > > I'm trying to manipulate json files using parser-json addon.
