SchemaCollection throws StackOverflowError when schema contains circular reference
----------------------------------------------------------------------------------

                 Key: CXF-2418
                 URL: https://issues.apache.org/jira/browse/CXF-2418
             Project: CXF
          Issue Type: Bug
          Components: Aegis Databinding
    Affects Versions: 2.2.3
            Reporter: Fried Hoeben


When a schema contains a reference to an element inside itself, or there is another circular
reference between schemas,  SchemaCollection.addCrossImports() goes into infinite recursion
ending with a StackOverflowError.

Sample stack (before the error):
