xsltc: How to find out java.net.SocketException as reason of TransformerException ?

[St...@avinci.de]

Hi,
 
i changed my transformations in a web-application from Xalan to XSLTC, but since some transformations only work with Xalan (because of bad stylesheets) i have a "mixed mode".
 
The Transformers are serializing directly to ServletOutputStreams. 
 
In an older (Xalan-only) version, the TransformerException wrapped a java.net.SocketException 
if the user had closed the browser during serialisation. 
I 've been able to check it with .getCause() and ignored it because it's not really an Error.
 
Now, if Xalan is transforming, it somehow wraps to a java.lang.RuntimeException (which holds the SocketException only in its stacktrace) and i can't figure out if it's just because the Browser was closed (can't get nested Exception) - so i throw it (wrapped into my own "ViewProcessingException"). 
 
If XSLTC is transforming, a org.apache.xml.utils.WrappedRuntimeException is thrown and i can find the
SocketException and everything is fine. 
 
In the case of Xalan I think i can't ignore those RuntimeExceptions (wrapped by TransformerExceptions) too, because they may have other reasons and i don't want to seek inside the message / stacktrace for the
"Connection reset by peer: socket write error" pattern.
 
Does someone has an idea what to do ?
Will it be changed to a WrappedRuntimeException or a nested SocketException later ?
Do i have a bad mix of jars ?

I use Xalan 2.4.1, IBM Websphere and this is the stacktrace:
 
ERROR:  'java.net.SocketException: Connection reset by peer: socket write error'
