Where is the latest Tinder source code? The tinder.jar file found in the latest OpenFire ( v3.10.0 ) project contains different method signatures ( e.g. asBareJID() ) than is documented in the "latest" Tinder version 1.2.2. Clearly, the OpenFire folks are using a different version of Tinder other than v1.2.2.
At the time of writing, what is in Openfire is a snapshot version of Tinder (based on the upcoming version 1.3.0). This is why there is a mismatch in signatures.
