Waldemar Prabucki, I remember we fixed some issues related to meta-data retrieval in the 5.x time frame. It was related to the collection of metadata in ExecutableMetadata and its builder (IIRC, the indeterministic behavior was caused by relying on iteration order of a hash set effectively). Unfortunately, 4.3 isn't maintained in community any longer, so there is not much we can do right now. It'd be different if you had an active JBoss EAP subscription; if not your best option is to try and fix the issue yourself I'm afraid.
