[jira] [Updated] (XMLBEANS-378) Add system property to allow
override of default piccolo parser
[ https://issues.apache.org/jira/browse/XMLBEANS-378?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.

> 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.
