             Bug #: 51142
           Summary: Offer possible resolution of
                    StringIndexOutOfBoundsException in
                    Request.updateCounters when AJP packetSize is too
                    small.
           Product: Tomcat 6
           Version: 6.0.28
          Platform: Macintosh
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Connectors
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: asfbugzilla-m@eghm.net
    Classification: Unclassified


I submitted a patch on the review board
https://reviews.apache.org/r/595/diff/#index_header to improve the error
message If the AJP packetSize is not large enough.  As is:

org.apache.coyote.ajp.AjpAprProtocol$AjpConnectionHandler process               
SEVERE: Error reading request, ignored
