ConstraintDeclarationException on JAX-RS/EJB Methods with List/Set query parameter ---------------------------------------------------------------------------------- Key: WFLY-11566 URL: https://issues.jboss.org/browse/WFLY-11566 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 14.0.0.Final, 15.0.1.Final Reporter: Alexander Wagner Assignee: Alessio Soldano Priority: Critical Like described in the thread https://developer.jboss.org/thread/278822 you got an exception if you call methods on JAX-RS endpoints which are also e.g. a stateless EJB and have Set or List as query parameters. As a workaround we use the "@Context UriInfo info" as parameter an read the parameter manually. As a downside this parameters are missing than in automated api generation with e.g. swagger.
