java.lang.StackOverflowError in XString.equals()

           Summary: java.lang.StackOverflowError in XString.equals()
           Product: XalanJ2
           Version: CurrentCVS
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xpath
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: Wolfram.Eisert@dresdner-bank.com


In some special cases I get a StackOverflowError in method equals(XMLString), 
line #444 [ if (!obj2.hasString()) return obj2.equals(this); ]

I think this can occur if to XStringForChars-objects are compared, and both
objects haven't been used before. Than the hasString()-method of
XStringForChars returns false for both, resulting in an endless loop.

I patched XStringForChars method hasString() to return always true,
which works for me.

Don't know if this is the right way to solve this bug.
