[~mlabuda] The hot code replace dialog shows up for me even if I dont manually connect the JMX. 
The steps for me:
# ASSERT: have jboss-helloworld running in OpenShift (create it via eap64-basic-s2i template), the source code for it imported to a workspace project and a server adapter for it 
# EXEC: open HelloService and change it to the following:
{code:title=HelloService}
public class HelloService {

    private static final String MAGIC_STRING = "42";
	
    String createHelloMessage(String name) {
        return "Hello " + name + ", the magic string is " + MAGIC_STRING + "!";
    }

}
{code}
and save the editor
Result:
"Hot code replace failed" dialog pops up, which is expected.

I filed the issues due to its poor usability to JBIDE-23602.

# EXEC: in "Hot Code Replace Failed" dialog: hit "Restart Module"
# EXEC: unfold the server adapter and see in what state the JMX node and the adapter is:
Result:

The adapter is synchronized for me, and the JMX is now connected.

[~mlabuda] What makes you think that debugging is out-of-sync as stated in the steps above?
I though can confirm that any change from now on - even non-structural changes - will trigger the "Hot Code Replace Failed" dialog.
[~rob.stryker] Can you please chime in and comment the fact that the dialog now always shows up?

> When enabling debug mode on an EAP server deployed on OpenShift, locally changing a class file will :
> - work sometimes when only the content of the method changed, but could fail in some other occasions with the Debugger saying the JDK is out of sync
> - will always fail if a method signature changed, the debugger saying JDK is out of sync
> Restarting the deployed module (with the .dodeploy flag) doesn't fixes the issue (as opposed to the same tweak ahen running on a local EAP server)
> This may be caused by running OpenJDK? Does it support the same level of debugging as Oracle JDK?
