Piccolo XML Parser for Java

Some applications like soap-webservices call up the parser with a
CoyoteInputStream. Unfortunately MLStreamReader.reset() ->
fillByteBuffer() --> CoyoteInputStream.availible() returns 0. So
PiccoloLexer.yylex() throws an exception "XML declaration is not
well-formed".

Probably The Servlet InputStream has a design flaw witch will not
be fixed. The first read() switches between charmode and
bytemode and availible() can't return the correct number until
the decision is made.
