Jacob Danner reassigned XMLBEANS-155:
-------------------------------------

    Assignee: Jacob Danner  (was: Yana Kadiyska)

> performance leak in XmlObject.selectPath()
> ------------------------------------------
> 
> Key: XMLBEANS-155
> URL: https://issues.apache.org/jira/browse/XMLBEANS-155
> Project: XMLBeans
> Issue Type: Bug
> Components: XmlObject, XPath
> Affects Versions: Version 1.0.3
> Environment: Win2k
> Reporter: Alexander Heinrich
> Assigned To: Jacob Danner
> 
> It seems that selectPath on XmlObject keeps references to some internal data (might \
> be cursors) that cannot be freed by the user (i.e. there's nothing for XmlObject \
> like clearSelections for XmlCursor). After extensive use of selectPath the system \
> slows down more and more. How I found this bug: I have large XML documents (>5 MB) \
> and use selectPath to retrieve an array of similar objects in this document. Every \
> time I reload the document (and invoke selectPath again) the loading process takes \
> a little longer than before... When I substitute the selectPath statement by some \
> other code that does the same but without using selectPath the time for loading \
> documents stays constant. If you need exemplary code email me: \
> alexander.heinrich@bluescarab.de
