> I use Karaf as a runtime to host my Apache Camel routes. They are
> mostly plain blueprint .xmls that are installed and deployed with the
> blueprint handler.  I make heavy use of xsl tranformations and have in
> the past used Xalan but am moving to Saxon for xslt/xpath 2.0.
> On 4.2.1 I don't have any issues installing and using either Xalan or
> Saxon bundles, but on 4.2.2, once either are installed I can no longer
> install through blueprint. It looks to be the result of the change for
> "Set the secure processing feature on TransformerFactory instances" in
> XmlUtils in commit de4c413925379913ffb3bf96ead7edc2dba98d4b. That
> commit sets XMLConstants.ACCESS_EXTERNAL_DTD and neither Xalan nor
> Saxon support that property. From what I've read searching for that
> error I believe external DTD isn't in the purview of transformation
> but in the document parser.
> Note that it is after a restart of Karaf after installing Saxon that I
> get the exception when trying to install another blueprint bundle. I
> believe a transfomer is already created from the default
> com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImp.
> Has anyone else seen this?
> Thanks.
