ClassNotFoundException: javax.sql.RowSet ---------------------------------------- Key: WFLY-4783 URL: https://issues.jboss.org/browse/WFLY-4783 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 9.0.0.CR2 Environment: Windows 7, Java 8u45 (64 bit) Reporter: Greg Jewell Assignee: Stuart Douglas I downloaded the WF9 CR2 release this morning and have been testing functionality. A new exception has appeared with this release. This did not happen with a source release that was downloaded and built between CR1 and CR2, so was just introduced in the last week or so. We have a Flex application that is throwing the following exception as it's being loaded: [BlazeDS]javax/sql/RowSet {noformat} java.lang.NoClassDefFoundError: javax/sql/RowSet at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:198) at flex.messaging.messages.AbstractMessage.writeExternal(AbstractMessage.java:444) at flex.messaging.messages.AsyncMessage.writeExternal(AsyncMessage.java:140) at flex.messaging.messages.AcknowledgeMessage.writeExternal(AcknowledgeMessage.java:94) at flex.messaging.messages.AcknowledgeMessageExt.writeExternal(AcknowledgeMessageExt.java:55) at flex.messaging.io.amf.Amf3Output.writePropertyProxy(Amf3Output.java:594) at flex.messaging.io.amf.Amf3Output.writeCustomObject(Amf3Output.java:532) at flex.messaging.io.amf.Amf3Output.writeObject(Amf3Output.java:112) at flex.messaging.io.amf.Amf0Output.writeObject(Amf0Output.java:206) at flex.messaging.io.amf.AmfMessageSerializer.writeObject(AmfMessageSerializer.java:196) at flex.messaging.io.amf.AmfMessageSerializer.writeBody(AmfMessageSerializer.java:186) at flex.messaging.io.amf.AmfMessageSerializer.writeMessage(AmfMessageSerializer.java:142) at flex.messaging.endpoints.amf.SerializationFilter.invoke(SerializationFilter.java:198) at flex.messaging.endpoints.BaseHTTPEndpoint.service(BaseHTTPEndpoint.java:291) at flex.messaging.MessageBrokerServlet.service(MessageBrokerServlet.java:353) at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) at io.undertow.servlet.handlers.ServletHandler.handleRequest(ServletHandler.java:86) at io.undertow.servlet.handlers.security.ServletSecurityRoleHandler.handleRequest(ServletSecurityRoleHandler.java:62) at io.undertow.servlet.handlers.ServletDispatchingHandler.handleRequest(ServletDispatchingHandler.java:36) at org.wildfly.extension.undertow.security.SecurityContextAssociationHandler.handleRequest(SecurityContextAssociationHandler.java:78) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.servlet.handlers.security.SSLInformationAssociationHandler.handleRequest(SSLInformationAssociationHandler.java:131) at io.undertow.servlet.handlers.security.ServletAuthenticationCallHandler.handleRequest(ServletAuthenticationCallHandler.java:57) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.security.handlers.AbstractConfidentialityHandler.handleRequest(AbstractConfidentialityHandler.java:46) at io.undertow.servlet.handlers.security.ServletConfidentialityConstraintHandler.handleRequest(ServletConfidentialityConstraintHandler.java:64) at io.undertow.security.handlers.AuthenticationMechanismsHandler.handleRequest(AuthenticationMechanismsHandler.java:58) at io.undertow.servlet.handlers.security.CachedAuthenticatedSessionHandler.handleRequest(CachedAuthenticatedSessionHandler.java:72) at io.undertow.security.handlers.NotificationReceiverHandler.handleRequest(NotificationReceiverHandler.java:50) at io.undertow.security.handlers.SecurityInitialHandler.handleRequest(SecurityInitialHandler.java:76) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at org.wildfly.extension.undertow.security.jacc.JACCContextIdHandler.handleRequest(JACCContextIdHandler.java:61) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.servlet.handlers.ServletInitialHandler.handleFirstRequest(ServletInitialHandler.java:274) at io.undertow.servlet.handlers.ServletInitialHandler.dispatchRequest(ServletInitialHandler.java:253) at io.undertow.servlet.handlers.ServletInitialHandler.access$000(ServletInitialHandler.java:80) at io.undertow.servlet.handlers.ServletInitialHandler$1.handleRequest(ServletInitialHandler.java:172) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:199) at io.undertow.server.HttpServerExchange$1.run(HttpServerExchange.java:774) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.ClassNotFoundException: javax.sql.RowSet from [Module "deployment.Test.ear.test.war:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:205) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:455) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:404) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:385) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:130) ... 43 more {noformat} - See more at: https://developer.jboss.org/thread/260451#sthash.LJ3DCVsa.dpuf
