Fried Hoeben updated CXF-2418:
------------------------------
Attachment: cxf-schemaCollection.patch
Patch file that prevents the StackOverflowError, by ensuring that for each
xmlSchema we only check each schemaElement once for cross imports, i.e. if it
is encountered again it will be ignored.
> 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
> Attachments: cxf-schemaCollection.patch
>
>
> 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.
