Description

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.
