[jbosstools-issues] [JBoss JIRA] (JBIDE-20669) Unhandled event loop exception when connecting to WildFly/EAP in JMX Navigator

Unhandled event loop exception when connecting to WildFly/EAP in JMX Navigator ------------------------------------------------------------------------------ Key: JBIDE-20669 URL: https://issues.jboss.org/browse/JBIDE-20669 Project: Tools (JBoss Tools) Issue Type: Bug Components: jmx Affects Versions: 4.3.0.CR1 Reporter: Martin Malina Assignee: Rob Stryker Labels: regression, respin-a Fix For: 4.3.0.CR1 I'm getting exceptions when I connect to a running server in JMX Navigator. I first noticed this with WildFly 10, but then verified it happens for WildFly 8.2.1 and EAP 6.4 also. The connection is established. But the only thing that works is MBeans - you can double click them and they will open, or you can just click one and the Property view will show details. But if you try to view properties of the connection itself, you will get more errors. The initial error is this: {code} Unhandled event loop exception org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.core.runtime.AssertionFailedException: null argument:) at
