> -------------------------------------------------------------------------------------------------------------

> Key: XALANJ-2312
> URL: http://issues.apache.org/jira/browse/XALANJ-2312
> Project: XalanJ2
> Issue Type: Bug
> Affects Versions: 2.7
> Environment: Windows XP Home, Java 1.5
> Reporter: Thomas Mauch
> Assigned To: Brian Minchau
> Priority: Minor
>
> To prevent the processing of erroneous XSLT stylesheets, I wanted to add a
> ErrorListener which throws an error even if the warning function is called.
> As the warning function does not allow throwing a TransformerException, it
> wrap it in a RuntimeException:
> static class XMLErrorListener implements ErrorListener {
> public void warning(TransformerException exception) {
> throw new RuntimeException(exception);
> }
> I however noticed that I got fewer errors than were logged before. I found
> out that the function org.apache.xml.serializer.ToXMLStream.addAttribute()
> contains a catch (Exception e) {} clause which swallows all exception thrown.
> Swallowing all exceptions is IMHO considered bad style. I see no reason why I
> should not be able to decide that I want to treat even warnings as errors and
> stop processing immediately.
> Other XSLT warnings do not swallow a thrown exception and therefore allow me
> to stop the processing.
