Unhandled event loop exception when connecting to WildFly/EAP in JMX Navigator

XMLWordPrintable

    • Hide

      1. Create a server manually (at least that's what I did) - WildFly 8.2, EAP 6.4 or WildFly 10 (but probably any AS7-style server) - it can use fs operations or management, it's all the same
      2. Start the server
      3. Once the server is started, double-click on the server in JMX Navigator under Server Connections
      4. Wait until all the mbeans are loaded, then there will be an exception in the Error view - FAIL#1
      5. Right-click the server in JMX Navigator - there will be more errors in the Error view - FAIL#2

      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:
