[Andre Dietisheim (JIRA)]

     [ https://issues.jboss.org/browse/JBIDE-21857?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andre Dietisheim updated JBIDE-21857:
-------------------------------------
    Steps to Reproduce: 
EXEC: Create a new OpenShift EAP 6.4 application. Open New OpenShift application wizard, select eap64-basic-s2i template, proceed to next wizard page, change CONTEXT_DIR param to helloworld, click Finish and let import application to your workspace once you are prompted.
EXEC: Create a new OpenShift 3 server adapter for the application.
ASSERT: There is a started server adapter for the application in Servers view.
EXEC: Restart server adapter in debug mode.
ASSERT: Server adapter is in debug mode, synchronized. 
ASSERT: Dialog warning about failed HCR is shown.
EXEC: Click button Restart buttons in Hot Code Replace Failed dialog.
ASSERT: Module is deployed on a remote server.

RESULT: Debugger is out of sync.
EXPECTED RESULT: Debugger is back to sync.

EXEC: Make a HCR compatible change (in method body e.g. change returned message).
EXEC: Save editor.

RESULT: Hot Code Replace Failed dialog is shown.
EXPECTED RESULT: Change is propagated successfully, there is no HCR Failed dialog and debugger is in sync.

EXEC: Expand server adapter.
ASSERT: JMX is connected (bug JBIDE-21857, if it is disconnected, double click on the button and wait to connect).
EXEC: Rename method or add a field to class (e.g. in HelloService) = do HCR incompatible change in class structure.
EXEC: Save editor.
ASSERT: Dialog warning about failed HCR is shown.
EXEC: Click button Restart buttons in Hot Code Replace Failed dialog.
ASSERT: Module is deployed on a remote server.

>          Issue Type: Bug
>          Components: openshift
>    Affects Versions: 4.3.1.Beta2
>            Reporter: Fred Bricon
>            Assignee: Rob Stryker
>             Fix For: 4.4.2.Final, 4.4.3.AM1, 4.5.0.AM1
>
>         Attachments: HCRFailure.zip

>
> 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?
