[ https://issues.jboss.org/browse/JBIDE-15574?page=com.atlassian.jira.plugi... ] Rob Stryker commented on JBIDE-15574: ------------------------------------- I did make a commit to update the the server jars to beta1, as that was needed for integrations testing anyway (always stay on the top of the stream), but in reality, there are still issues when using a java 6 jre to run eclipse and communicate with a wildfly server. It appears the the NIO libraries have a requirement on API introduced in java7, specifically a class named ReflectiveOperationException. I think now it becomes basically a requirement to run eclipse with java7 if you expect to be communicating with wildfly unless we can get the nio stuff fixed. {code} java.lang.NoClassDefFoundError: java/lang/ReflectiveOperationException at org.xnio.ssl.JsseXnioSsl.<init>(JsseXnioSsl.java:81) at org.xnio.Xnio.getSslProvider(Xnio.java:221) at org.jboss.remoting3.remote.RemoteConnectionProvider.connect(RemoteConnectionProvider.java:188) at org.jboss.remoting3.EndpointImpl.doConnect(EndpointImpl.java:296) at org.jboss.remoting3.EndpointImpl.doConnect(EndpointImpl.java:251) at org.jboss.remoting3.EndpointImpl.connect(EndpointImpl.java:349) at org.jboss.remoting3.EndpointImpl.connect(EndpointImpl.java:337) at org.jboss.as.protocol.ProtocolConnectionUtils.connect(ProtocolConnectionUtils.java:80) at org.jboss.as.protocol.ProtocolConnectionUtils.connectSync(ProtocolConnectionUtils.java:99) at org.jboss.as.protocol.ProtocolConnectionManager$EstablishingConnection.connect(ProtocolConnectionManager.java:256) at org.jboss.as.protocol.ProtocolConnectionManager.connect(ProtocolConnectionManager.java:70) at org.jboss.as.protocol.mgmt.FutureManagementChannel$Establishing.getChannel(FutureManagementChannel.java:204) at org.jboss.as.controller.client.impl.RemotingModelControllerClient.getOrCreateChannel(RemotingModelControllerClient.java:148) at org.jboss.as.controller.client.impl.RemotingModelControllerClient$1.getChannel(RemotingModelControllerClient.java:67) at org.jboss.as.protocol.mgmt.ManagementChannelHandler.executeRequest(ManagementChannelHandler.java:115) at org.jboss.as.protocol.mgmt.ManagementChannelHandler.executeRequest(ManagementChannelHandler.java:90) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.executeRequest(AbstractModelControllerClient.java:236) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.execute(AbstractModelControllerClient.java:141) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.executeForResult(AbstractModelControllerClient.java:127) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.execute(AbstractModelControllerClient.java:71) at org.jboss.ide.eclipse.as.internal.management.wildfly8.Wildfly8Manager.execute(Wildfly8Manager.java:316) at org.jboss.ide.eclipse.as.internal.management.wildfly8.Wildfly8Manager.getServerState(Wildfly8Manager.java:257) at org.jboss.ide.eclipse.as.internal.management.wildfly8.Wildfly8ManagerService.getServerState(Wildfly8ManagerService.java:142) at org.jboss.ide.eclipse.as.management.core.JBoss7ManagerServiceProxy.getServerState(JBoss7ManagerServiceProxy.java:71) {code} Re-opening wildfly bug. -- This message is automatically generated by JIRA.
