Workaround was to replace @NotEmpty with @NotNull. see also: http://forum.hibernate.org/viewtopic.php?p=2339708#2339708 Stack-Trace: java.lang.IllegalArgumentException: could not instantiate ClassValidator at org.hibernate.validator.ClassValidator.createValidator(ClassValidator.java:287) at org.hibernate.validator.ClassValidator.createMemberValidator(ClassValidator.java:255) at org.hibernate.validator.ClassValidator.initValidator(ClassValidator.java:216) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:127) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:105) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:97) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:319) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1210) at org.hibernate.console.ConsoleConfiguration$2.execute(ConsoleConfiguration.java:317) at org.hibernate.console.execution.DefaultExecutionContext.execute(DefaultExecutionContext.java:65) at org.hibernate.console.ConsoleConfiguration.execute(ConsoleConfiguration.java:89) at org.hibernate.console.ConsoleConfiguration.buildSessionFactory(ConsoleConfiguration.java:312) at org.hibernate.eclipse.console.workbench.LazySessionFactoryAdapter.getChildren(LazySessionFactoryAdapter.java:41) at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.getChildren(BasicWorkbenchAdapter.java:88) at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.fetchDeferredChildren(BasicWorkbenchAdapter.java:94) at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:207) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) Caused by: java.util.MissingResourceException: Can't find resource in validator bundles, key validator.notEmpty at org.hibernate.validator.interpolator.DefaultMessageInterpolator.replace(DefaultMessageInterpolator.java:107) at org.hibernate.validator.interpolator.DefaultMessageInterpolator.initialize(DefaultMessageInterpolator.java:66) at org.hibernate.validator.interpolator.DefaultMessageInterpolatorAggerator.addInterpolator(DefaultMessageInterpolatorAggerator.java:37) at org.hibernate.validator.ClassValidator.createValidator(ClassValidator.java:283) ... 16 more java.util.MissingResourceException: Can't find resource in validator bundles, key validator.notEmpty at org.hibernate.validator.interpolator.DefaultMessageInterpolator.replace(DefaultMessageInterpolator.java:107) at org.hibernate.validator.interpolator.DefaultMessageInterpolator.initialize(DefaultMessageInterpolator.java:66) at org.hibernate.validator.interpolator.DefaultMessageInterpolatorAggerator.addInterpolator(DefaultMessageInterpolatorAggerator.java:37) at org.hibernate.validator.ClassValidator.createValidator(ClassValidator.java:283) at org.hibernate.validator.ClassValidator.createMemberValidator(ClassValidator.java:255) at org.hibernate.validator.ClassValidator.initValidator(ClassValidator.java:216) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:127) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:105) at org.hibernate.validator.ClassValidator.<init>(ClassValidator.java:97) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:319) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1210) at org.hibernate.console.ConsoleConfiguration$2.execute(ConsoleConfiguration.java:317) at org.hibernate.console.execution.DefaultExecutionContext.execute(DefaultExecutionContext.java:65) at org.hibernate.console.ConsoleConfiguration.execute(ConsoleConfiguration.java:89) at org.hibernate.console.ConsoleConfiguration.buildSessionFactory(ConsoleConfiguration.java:312) at org.hibernate.eclipse.console.workbench.LazySessionFactoryAdapter.getChildren(LazySessionFactoryAdapter.java:41) at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.getChildren(BasicWorkbenchAdapter.java:88) at org.hibernate.eclipse.console.workbench.BasicWorkbenchAdapter.fetchDeferredChildren(BasicWorkbenchAdapter.java:94) at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:207) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
