> Infinite loop in OMElement possible
> -----------------------------------
>
> Key: WSCOMMONS-182
> URL: https://issues.apache.org/jira/browse/WSCOMMONS-182
> Project: WS-Commons
> Issue Type: Bug
> Components: AXIOM
> Environment: Windows XP, Java 1.5_09, Axiom 1.1.1.
> Reporter: Ryan Nelsestuen
> Assignee: Andreas Veithen
> Attachments: InfinteLoopDemo.java
>
>
> > I discovered today that under certain circumstances you can create an
> > OMElementImpl that will go into an infinte loop if you call
> > getFirstElement(); The specific example I found is if you create an
> > OMElement via the SAXOMBuilder and pass the SAXOMBuilder and
> > incomplete/malformed series of events (example code below). The
> > workaround is to check isComplete() before calling getFirstElement(),
> > but it seems like there should be some other way to avoid this condition.
