Fabric - java.net.MalformedURLException: Unknown protocol: profile2

Solution Verified - Updated -


  • Red Hat Fuse
    • 6.3 Rollup 8 - build number 630347
    • 6.3 Rollup 9 - build number 630356
  • Fabric managed environment


  • After the restart of the container, we get the following error:
    java.net.MalformedURLException: Unknown protocol: profile2

  • The error is thrown randomly at various container restarts


This Bug ENTESB-9977 has been resolved, and the fix is included in JBoss Fuse 6.3 Rollup 12 or later.

Note: From JBoss Fuse 6.3 R12 onwards you can increase the default profile URL time-out of 40s to any higher value via the following command:

        profile-edit --pid io.fabric8.agent/config.profile.url.timeout='60' default   

As a possible workaround:

1 - Restart the bundle pax-web-jetty:

        container-connect <container>

        JBossFuse:admin@child5> osgi:list -l -t 0 | grep pax-web-jetty
        [ 147] [Active     ] [            ] [   30] mvn:org.ops4j.pax.web/pax-web-jetty/4.3.6
        JBossFuse:admin@child5> osgi:restart 147
        You are about to access system bundle 147.  Do you wish to continue (yes/no): yes

2 - Restart the concerned Fabric container, like following:

        container-stop <container_name>
        container-start <container_name>

Root Cause

Bug ENTESB-9977.
The default retry interval of 20 seconds was too short to retrieve the profile URL handler.
