Wildfly : ClassNotFoundException: org.apache.xerces.parsers.SAXParser when deploying - deployment

Question

I'm facing this error when deploying a war containing a spring-ws:
{"WFLYCTL0062: Composite operation failed and was rolled back. Steps that failed:" => {"Operatio
n step-2" => {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"FLUX-WSApp.war\".undertow-deploym
ent" => "org.springframework.beans.factory.BeanCreationException: Error creating bean
...
Caused by: org.xml.sax.SAXException: SAX2 driver class org.apache.xerces.parsers.SAXParser not found
java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser from [Module \"deployment.FLUX-WSApp.
war\" from Service Module Loader]
Caused by: java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser from [Module \"deploym
ent.FLUX-WSApp.war\" from Service Module Loader]"}}}}
So I looked if the module was loaded (he is):

}
I have another server where deploying this war doesn't cause error.
I can compare them, but I can't see any difference.(in standalone.xml particulary).
The jar and main/module.xml are the same on two servers. The acl are identicals.
cat ~/modules/system/layers/base/org/apache/xerces/main/module.xml

I cannot edit code of the deploying war, I'm not the developer, but I can de-compile it.
I noticed the only reference about org.apache.xerces is:
package org.springframework.instrument.classloading;
...
/**
* ClassLoader decorator that shadows an enclosing ClassLoader,
* applying registered transformers to all affected classes.
...
public class ShadowingClassLoader extends DecoratingClassLoader {
/** Packages that are excluded by default */
public static final String[] DEFAULT_EXCLUDED_PACKAGES =
new String[] {"java.", "javax.", "sun.", "oracle.", "com.sun.", "com.ibm.", "COM.ibm.",
"org.w3c.", "org.xml.", "org.dom4j.", "org.eclipse", "org.aspectj.", "net.sf.cglib",
"org.springframework.cglib", "org.apache.xerces.", "org.apache.commons.logging."};
Does somebody can help ?
Where should I look to ?

I have re-install completely wildfly. The problem doesn't occur any more.
