Type: Bug
Resolution: Done
Priority: Blocker
Fix Version/s: 9.0.0.CR2, 10.0.0.Alpha1
Affects Version/s: 9.0.0.CR1
Component/s: Clustering
Labels:
None

Steps to Reproduce:
Hide

Modify standalone-ha.xml as follows:

Set the JGroups default stack to "tcp"

Replace the MPING protocol with:

<protocol type="TCPPING"> <property name="timeout">30000</property> <property name="initial_hosts">127.0.0.1[7600]</property> <property name="port_range">0</property> <property name="num_initial_members">1</property> </protocol>

Deploy a distributable app

(This can also be reproduced on OpenShift using the WildFly 9 cartridge as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1220300.)

Description

Protocol properties are never applied, the check for applying properties is done on the legacy resource that only registers operation tranformation on old the old property address.

Original report:

When the JGroups subsystem is configured to use TCPPING, the following error occurs when deploying a distributable app:
