Rodrigo Setti updated XMLBEANS-378:
-----------------------------------

    Attachment: xmlbeans-system-default-xml-reader.diff

Hi,

I have some cases in my application that piccolo parser enter's a infinite loop and \
eventually I get into a heap exception.

Therefore I replaced it with the platform's default parser, and it worked great. The \
time performance difference is unnoticeable.

I'm providing a patch that allow xmlbeans to select the platform's default Sax \
Parser, instead of relying in a another configuration option.

> Key: XMLBEANS-378

> Project: XMLBeans
> Issue Type: Wish

> Affects Versions:  Version 2.3
> Reporter: Kevin Jones
> Priority: Minor

> It would be useful to allow the default piccolo parser to be replaced by other SAX2 \
> conformant parsers that may other more features/performance without having to make \
> application code changes.  This can be done by some minor changes to the Store \
> Locale.java mechanism that caches piccolo parsers per thread. In a trial \
> implementation (see attached patch) an xmlbeans specific system property is added \
> which has the same meaning as the 'org.xml.sax.driver' property, i.e. it specifies \
> the name of a org.xml.sax.XMLReader class. If the property is set this parser is \
> instantiated instead of a piccolo parser.  The patch passes checkintest when  the \
> property "org.apache.xmlbeans.xmlreader" is set to \
> "com.sun.org.apache.xerces.internal.parsers.SAXParser" on a jdk1.5.0_15 on WIN32.
