After installing the code gen plugin, you restart the eclipse and click on the Axis2 Code Generator in the Axis2Wizards This log props out

An error has occurred. See error log for more details.
loader constraint violation in interface itable initialization: when resolving method "org.apache.xerces.dom.CoreDocumentImpl.getDomConfig()Lorg/w3c/dom/DOMConfiguration;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, org/apache/xerces/dom/CoreDocumentImpl, and the class loader (instance of <bootloader>) for interface org/w3c/dom/Document have different Class objects for the type org/w3c/dom/DOMConfiguration used in the signature.

In addition this is the error log which throws up

I reproduced the issue when I created a new wsdl in a java project in eclipse and then tried to access the Axis2CodeGenerator.When I click on it the above screen props out

Please look into it asap.
