Hi folks, I'm trying the PEAR class loaders in UIMA 2.2. I think I found an issue that, if a PEAR description file is specified in the aggregate analysis engine description, the session object returned from the method org.apache.uima.analysis_component.JCasAnnotator_ImplBase.getContext().getSession() from the related annotator will be different from other annotators. In other words, the annotators cannot share the same session object if the PEAR class loader is used.
Here is more detail on the situation. I have two annotators. Both of them sharing the same piece of information via the Session object (Session session = getContext().getSession();). I assume that both annotators will have access to the same session object. I tried it and found the inconsistent behavior between the following cases: Case 1: The aggregate analysis engine description contains full descriptions of both annotators (no import tags). Case 2: The aggregate analysis engine description contains import tags with the PEAR description files specified (xxx_pear.xml) for both annotators. In case 1, for both annotators, the *same* session object are returned from the method org.apache.uima.analysis_component.JCasAnnotator_ImplBase.getContext().getSession(). However in case 2, the *different* session objects are returned from the method. I'm not sure if it's a bug or expected behavior. Could someone please shed some light? Please feel free to let me know if you need more information. Thanks in advance, Danai Wiriyayanyongsuk
