| Hi, Anyway the problem occurs on many different methods and classes. Constraints used are simplest use cases of javax.validation.constraints.*. No methods are being overridden in this scenario. The annotations are on class with implementation - no interfaces involved. Class hierarchy is as follows: Object -> RestServices (TX-Management) -> MasterDataApi (class with annotations) However MasterDataApi is an Stateless EJB. javaMethod from the example contains Method from MasterDataApi class. instance from the example is an instance of the EJB Proxy. Strange is that for calls to the same service once it works fine and in other case not (no pattern found, sometimes each call is ok, sometimes every second or third call is not ok). However all the objects involved in initialization of hibernate validator instance are the same. Unfortunatelly I have to use version 4.3.2 as I have to use Bean Validation 1.0 (client requirement to WebSphere 8.0.x with Java 1.6 and few other frameworks) |
