[jboss-jira] [JBoss JIRA] (AS7-4828) JGroups subsystem protocol properties should support expressions

[Richard Achmatowicz (JIRA)]

    [ https://issues.jboss.org/browse/AS7-4828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714108#comment-12714108 ] 

Richard Achmatowicz commented on AS7-4828:
------------------------------------------

As suspected, the protocol property processing does not make use of CommonAtttributes.VALUE, and so any expressions pass through undetected, despite the fact that CommonAttributes.VALUE blocks them.

So the situation is that (i) expressions are "not supported" in 7.1.2 as CommonAtttributes.VALUE has setAllowExpression(false) but (ii) expressions get through and are partially supported by JGroups through an implementation error (bug). And because of that, some users may be making use of the feature that is not supposed to be enabled.

If we did incorporate AS7-4828 in 7.1.x, this would not interfere with users current usage. Given this newly revealed circumstance, Brian, WDYT?
