Problem with json-parser
by Rafael Pestano
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.

JDK 8
by George Gastaldi
Hello Forge users,
For the next minor release, I'd like to make JDK8 the minimum requirement.
The JBoss Tools team is already using JDK8 as the minimum requirement for
their new versions. We are already running our build in JDK8 (with sources
set to 1.7 still)
Is there any objection? Say it now or forever hold your peace, because the
Forge train never stops ;)
Best Regards, love you all!

Re: [forge-users] [forge-dev] JDK 8
by George Gastaldi
I created a poll to gather feedback and help in our decision to upgrade the
minimum JDK version to 8: http://goo.gl/forms/yqGss6gxOA
I appreciate if you could help us by answering just those 2 questions, it
should take some seconds.
Thank you!
