> The problem being that InvocationHandlers in the classes AbstractImageSessionContext and ObservableStream do not handle InvocationTargetException properly, and the exception is propagated up to the proxied interface where InvocationTargetException is not specified.
> I am not sure if you accept pull requests on Github, anyway here it is https://github.com/apache/xml-graphics-commons/pull/1
