I am using bean validation in my application. When there is no constraint validation errors everything works nicely. Every time there is a validation error, Glassfish throws the following exception:
Caused by: java.lang.ClassNotFoundException: javax.validation.groups.Default: java.net.MalformedURLException: Unknown protocol: osgi
at com.sun.corba.ee.impl.util.JDKBridge.loadClassM(JDKBridge.java:325)

The bean-validation.jar is present in glassfish/modules folder. The startup doesn't throw any exceptions regarding validation.
PS. Note that we are using remote beans with CORBA.
Reproducable on GlassFish 3.1.2.2 and 3.1.1.
I traced this problem to serialization of the ConstraintValidationException through CORBA. Somehow the bean-validation module is not loaded properly with osgi and the javax.validation.groups.Default class is missing. I made a quick workaround so that the ConstraintValidationException is intercepted and never sent through CORBA. Instead the validation error information is gathered in a custom Exception class that can be actually serialized through the services.
