Matt Benson updated JXPATH-73:
------------------------------
Attachment: jxpath-73.patch.txt
> ValueUtils should catch IndexOutOfBoundsException instead of
> ArrayIndexOutOfBoundsException (for XmlBeans support)
> ------------------------------------------------------------------------------------------------------------------

> Key: JXPATH-73
> URL: https://issues.apache.org/jira/browse/JXPATH-73
> Project: Commons JXPath
> Issue Type: Bug
> Affects Versions: 1.2 Final
> Environment: XmlBeans with JDK 1.4.2 and JXpath 1.2
> Reporter: James Schopp
> Fix For: 1.3

> Basically, I want to do createPathAndSetValue on an XmlBean . But, my xpath
> statement inlcudes a collection (an array, actually), so the missing elements
> in the array need to be created.
> JXPath checks for this condition (ie. that array elements are missing and
> need to be created) by catching an ArrayIndexOutOfBoundsException.
> Unfortunately, XmlBeans does not throw that type of exception. It throws an
> IndexOutOfBoundsException exception instead. So, instead of detecting that
> the array is too small and needs to be grown (by calling my AbstractFactory),
> it just propogates the exception up the chain.
> The fix is quite simple: on line 423 of ValueUtils, just change the "catch"
> clause to catch a "IndexOutOfBoundsException" instead. This should not break
> any existing code since ArrayIndexOutOfBoundsException is actually a subclass
> of IndexOutOfBoundsException anyway.
> I made this fix to my local source tree, and everything works perfectly (ie.
> existing code did not break, but now I can also use JXPath on top of my
> XmlBeans beans too with my own custom AbstractFactory).
> Thanks!
> James
