XMLString::subString failure when len(source)==0

           Summary: XMLString::subString failure when len(source)==0
           Product: Xerces-C++
           Version: 2.1.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Utilities
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: Martin.Ebourne@csfb.com


XMLString::subString(buffer,"",0,0) would not seem outrageous. Gives 
ArrayIndexOutOfBoundsException.

This test in the subString code would seem to be the culprit:

if (startIndex > srcLen-1

This appears in both char* and XMLCh* versions.

PS. This could also be generalised to
XMLString::subString(buffer,text,textLen,textLen)
