Description:
Hi.

I'm working on an application that needs to serialize trees of wsdl2java-generated objects e.g. to write them to disk as XML documents.  I'm using code that looks like:

        Writer out = new FileWriter("build/ECReport-test.xml");
        SerializationContext ser = new SerializationContext(out);
        ser.setPretty(true); 
        ser.serialize(new QName("ECReport"), new AttributesImpl(), output, null, false, Boolean.FALSE);
        out.flush();
        out.close();

When I tried running the code it didn't serialize, so I looked at SerializationContext and found a bug in getSerializerFromClass(). 

        try {
            Method method = javaType.getMethod(
                    SERIALIZER_METHOD, SERIALIZER_CLASSES);
            if (method != null) {
                serializer = (Serializer) method.invoke(null,
                     new Object[] {msgContext.getEncodingStyle(), javaType, qname});
            }
       } catch (Exception e) {
       }

Because msgContext is null the call to msgContext.getEncodingStyle() will cause a NullPointerException.  The NPE was being thrown away because of the catch(Exception e).  I'll attach a patch that fixes this, and one downstream bug in BeanSerializer and seems to work for me.
