[jboss-jira] [JBoss JIRA] (JGRP-1505) GroupRequest: received and suspected is counted twice

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714185#comment-12714185 ] 

Bela Ban commented on JGRP-1505:
--------------------------------

This is a regression, due to the change in semantics in which we allow a received response to also be suspected (e.g. later). In previous version, a response had to be either received or suspected, but couldn't be both...

> When we have 3 members A,B,C and invoke a blocking RPC, if a member does both receive a valid response and is suspected, both events count twice, e.g.:
> A: received     / non-suspected (1)
> B: received     /     suspected (2) // wrong, should count as 1 !
> C: non-received / non-suspected (0)
> So instead of blocking the caller until C is suspected, or we get a valid response from C, the caller in unblocked because we count the valid response *and* the suspicion of B *twice* !
> This leads to premature termination of a blocking RPC !
