Currently, rpl_semi_sync is failing in PB due to the warning message: "Slave SQL: slave SQL thread is being stopped in the middle of " "applying of a group having updated a non-transaction table; " "waiting for the group completion ..." The problem started happening after the fix for BUG#11762407 what was automatically suppressing some warning messages. To fix the current issue, we suppress the aforementioned warning message and exploit the opportunity to make the sentence clearer.
