[Marián Labuda (JIRA)]

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

Marián Labuda updated JBIDE-21857:
----------------------------------
    Steps to Reproduce: 
ASSERT: Have a running OpenShift java application on OpenShift with a server adapter. For example the one instantiated by eap64-basic-template.
EXEC: Create a new OpenShift 3 server adapter for the application.
EXEC: Restart server adapter in debug mode.
EXEC: Rename method or add a field to class.
ASSERT: Dialog warning about failed HCR is shown.
EXEC: Reload the module.
EXEC: Make change HCR compatible (e.g. method body).

RESULT: HCR compatible change hasn't take effect.
EXPECTED RESULT: Upon module restart and HCR compatible change this change will be visible, debugger get back to sync.

EXPECTED RESULT: Upon module restart and HCR compatible change this change will be visible.
    Rename a private method in a class
    Observe: you get a dialog saying the HCR has failed and offering to reload the module
    Reload the module
    Now make a further change that is HCR-compatible (add a printf)
    Observe: the HCR works.

>          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?
