Document ID 2046582.1 "Java 6u101, 7u85 and 8u51 and Later Releases Break Enterprise Manager Ops Center Agent Controller to Proxy Communication"
The assets with Java upgraded to the versions mentioned under 'Occurrence' section will show a red question mark against them under the Assets sections of the Navigation pane on the Browser User Interface.
There will be an alert in the 'Message Center' section, with the Alert Source as the hostname of the unreachable Agent Controller, saying 'The asset can no longer be reached'.
The problem appears after you have upgraded to latest java version some of the components.
Note that the java upgrade could be done because of an OS patching (going to latest Solaris CPU for example)
