Can't deploy an EJB to a WildFly 10 server migrated from EAP 6.4 ---------------------------------------------------------------- Key: WFLY-5850 URL: https://issues.jboss.org/browse/WFLY-5850 Project: WildFly Issue Type: Bug Components: EJB Reporter: Ladislav Thon Assignee: Jason Greene Priority: Critical I just tried to migrate a {{standalone.xml}} server from clean EAP 6.4.0 to WildFly 10.0.0.CR4 and then deploy the {{server-side}} part of the {{ejb-remote}} quickstart: {code} git clone git@github.com:jboss-developer/jboss-eap-quickstarts.git cd jboss-eap-quickstarts/ git checkout -b 6.4.x origin/6.4.x cd ejb-remote/server-side/ mvn clean package -s ../../settings.xml cd target unzip .../jboss-eap-6.4.0.zip unzip .../wildfly-10.0.0.CR4.zip cp jboss-eap-6.4/standalone/configuration/standalone.xml wildfly-10.0.0.CR4/standalone/configuration/test.xml ./wildfly-10.0.0.CR4/bin/standalone.sh -c test.xml --admin-only # on a separate console ./wildfly-10.0.0.CR4/bin/jboss-cli.sh -c --controller=localhost:9999 /subsystem=threads:remove /extension=org.jboss.as.threads:remove /subsystem=web:migrate shutdown # on the original console cp jboss-ejb-remote-server-side.jar wildfly-10.0.0.CR4/standalone/deployments/ ./wildfly-10.0.0.CR4/bin/standalone.sh -c test.xml {code} What I get is this horrible stack trace: {code} 15:35:50,913 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.deployment.unit."jboss-ejb-remote-server-side.jar".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.unit."jboss-ejb-remote-server-side.jar".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "jboss-ejb-remote-server-side.jar" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:154) [wildfly-server-2.0.0.CR8.jar:2.0.0.CR8] at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) [jboss-msc-1.2.6.Final.jar:1.2.6.Final] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) [jboss-msc-1.2.6.Final.jar:1.2.6.Final] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [rt.jar:1.8.0_66] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [rt.jar:1.8.0_66] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.8.0_66] Caused by: javax.validation.ValidationException: Unable to create a Configuration, because no Bean Validation provider could be found.

This suggests that something (probably the EJB subsystem?) doesn't correctly parse/serialize the legacy configuration. Or something like that.
