Dependent class: oracle.dbtools.raptor.oviewer.base.ViewerAddin$XMLParser
Configuration: extension jar in C:\sqldeveloper\sqldeveloper\sqldeveloper\extensions
This load was initiated at ide-global:220.127.116.11.0 using the loadClass() method.
The missing class is not available from any code-source or loader in the system.
But I look for this extension and it is located in the appropiate folder, the same that loader say it dont find. and also I have open a copy of this jar file to be sure it have the class and yes it have this class, also give another error with another class in the same jar file and also this class exist.
