Thorsten Hersam updated CXF-7905:
---------------------------------
Description:
I am having the following issue with a SOAP request of my software deployed in
Wildfly 13.0.0.Final. Wildfly makes use of CXF core in version
3.2.4-jbossorg-1. Of this version I was unable to find sources but my issue
persists with any or the 3.2 versions of CXF.
The same software was previously deployed without any issues on Wildfly
10.0.1.Final which uses CXF 3.1.6.
Upon authentification at a SOAP web service I now receive the following
exception:
{code:java}
12:26:29,314 WARNING [org.apache.cxf.phase.PhaseInterceptorChain] (default
task-1) Interceptor for
{http://endpoint.soap.webservice.logicaldoc.com/}SoapAuthServiceService#{http://ws.logicaldoc.com}login
has thrown exception, unwinding now: java.lang.NullPointerException

{code}
jaxb MarschallerImpl fails when org.apache.cxf.common.jaxb.JAXBUtils tries to
set an EscapeHandler of null.
+Possible Solution+
Adding a null check at org.apache.cxf.common.jaxb.JAXBUtils.setEscapeHandler as
indicated below. Solves the issue.
{code:java}
public static void setEscapeHandler(Marshaller marshaller, Object
escapeHandler) {
try {
String postFix = getPostfix(marshaller.getClass());
if (postFix != null && escapeHandler != null) {
marshaller.setProperty("com.sun.xml" + postFix +
".bind.characterEscapeHandler", escapeHandler);
}
} catch (PropertyException e) {
LOG.log(Level.INFO, "Failed to set MinumEscapeHandler to jaxb
marshaller", e);
}
}
{code}
While a PropertyException seems to be okay for CXF a null escapeHandler Object
leads to escapeHandler.getClass().getName() called by jaxb MarshallerImpl just
as it was trying to throw a PropertyException.
+Why is the EscapeHandler null+
A null EscapeHandler can occur when
org.apache.cxf.common.jaxb.createEscapeHandler() actual return delegate
ProxyHelper.getProxy() throws an Exception.
In my case a the following Exception is thrown:
{code:java}
Caused by: java.lang.IllegalArgumentException: interface

org.apache.cxf.endpoint.Client does not seem to be visible of the combined
classloader constructed in ProxyHelper.getProxyInternal().
I am not utterly familiar with ClassLoaders but I find it strange that
org.apache.cxf classes - which are calling a ProxyHelper which constructs a
ClassLoader for "com.sun.xml.bind.marshaller.CharacterEscapeHandler" - fail
because another org.apache.cxf interface is not visible.
