thanks Jean-Louis.  i tried excluding xalan maven artifact from the pom but then FOP doesn't work.  i might try to create a reproducer using tomee webapp archetype if possible

This usually indicates you have the same class loaded into 2 different
classloaders which makes them different.
In this scenario, I would check if you don't have duplicate xalan jars in
tomee/lib and in the WEB-INF/lib of your application.

Hope it helps

i have a couple of problems...

i have not been able to upgrade from TomEE 7.0.3 to 7.0.4 or 7.0.5 due to
the error (it works fine in 7.0.3)
java.lang.ClassCastException: org.apache.xml.dtm.ref.DTMManagerDefault
cannot be cast to org.apache.xml.dtm.DTMManager

which occurs when i run the following code for Apache FOP
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL filepath = classLoader.getResource(xslPath);
Reader xsl = new InputStreamReader(filepath.openStream());
TransformerFactory transformerfactory = TransformerFactory.newInstance();
StreamSource ssXsl = new StreamSource(xsl);
Templates templates = transformerfactory.newTemplates(ssXsl);
Transformer transformer = templates.newTransformer();
StringReader reader = new StringReader(xml);
StringWriter writer = new StringWriter();
transformer.transform(new StreamSource(reader), new StreamResult(writer));
out = writer.toString();
writer.close();
reader.close();

My new problem is that I am using 7.0.5 in development and this code
(using a CXF webClient) works perfectly.
Collection<? extends Integer> leadids = webClient.accept(MediaType.APP
LICATION_JSON).getCollection(Integer.class);
List<Integer> leadids_ = new ArrayList<>(leadids);

But when I deployed it to 7.0.3 it does not work.  Is there any way to
slurp some JSON formatted like this
[1,2,3,4]

I tried creating a wrapper like below but it didn't match
public class listWrapper {
     private List<Integer> list;
     // ...
}
