[JBoss JIRA] (WFCORE-1848) Domain server process' main thread can terminate without triggering process exit
by Brian Stansberry (JIRA)
Brian Stansberry created WFCORE-1848:
----------------------------------------
Summary: Domain server process' main thread can terminate without triggering process exit
Key: WFCORE-1848
URL: https://issues.jboss.org/browse/WFCORE-1848
Project: WildFly Core
Issue Type: Bug
Components: Domain Management
Reporter: Brian Stansberry
Assignee: Brian Stansberry
If a thread completes the DomainServerMain main(String[] args) method, the process must exit. Currently that may not occur, as this stack trace reported while manually checking the WFCORE-1844 fix showed:
{code}

{code}
If the process does not exit, it is no longer under the control of the PC or HC and the only thing they can do with it is kill it. So it should kill itself.

[JBoss JIRA] (ELY-627) Elytron introduces SSL/TLS protocol constraints
by David Lloyd (JIRA)
[ https://issues.jboss.org/browse/ELY-627?page=com.atlassian.jira.plugin.sy... ]
David Lloyd commented on ELY-627:
---------------------------------
The "openssl.TLSv1.1" is not a valid value for protocol, nor will it be. I think we may have to revisit EAP7-576 if that is the resolution to that issue; to use OpenSSL it should be a provider selection, not a protocol selection.

I am rising to blocker as it is not possible to use openssl protocols introduced by https://issues.jboss.org/browse/EAP7-576. For example for openssl.TLSv1.1 we get:
