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?
JGroups subsystem protocol properties should support expressions
