[jboss-jira] [JBoss JIRA] (WFCORE-2784) Host controller should allow passing jvm parameters to servers

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-2784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13403887#comment-13403887 ] 

Brian Stansberry commented on WFCORE-2784:
------------------------------------------

The server vm config needs to come via the <jvm> element; we don't want it being controlled by the HC VM settings, as the server can be running a completely different JDK from the HC. And trying to intelligently mix the two sounds like a bug nest.

But being clever about ignoring stuff that we know won't work makes sense if we can. I forget how the permgen/metaspace stuff worked (i.e. how the HC knew the server's VM version) but it seems like it must have since it's the same kind of problem.

> It should be possible passing jvm options from host controller to servers runing in it.
> One such example is passing -ea to servers if passed to host controller
> other example is passing JDK9 specific parameters trough
