             Summary: Selector parser shouldn't allow either % or _ character as an ESCAPE
character in a LIKE comparison
                 Key: QPID-5805
                 URL: https://issues.apache.org/jira/browse/QPID-5805
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker
    Affects Versions: 0.28
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher
            Priority: Minor


a selector expression similar to:

qpid.subject LIKE '%%%' ESCAPE '%'

makes no sense. In general the excape character only needs to be chosen for aesthetic reasons
since it only has to quote %,_, and itself. It nver needs to be % or _ and these choices make
no sense since then you would not be able to have the unquoted version of them anywhere in
the string.
