Calling jcas.getType for a type that is not defined in the descriptor leaves
the JCAS in an inconsitent state
-------------------------------------------------------------------------------------------------------------
Key: UIMA-738
URL: https://issues.apache.org/jira/browse/UIMA-738
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.2.1
Reporter: Adam Lally
Assignee: Adam Lally
Fix For: 2.3
The following code illustrates the problem:
public void testUndefinedType() throws Exception {
//create jcas with no type system
JCas jcas = CasCreationUtils.createCas(new TypeSystemDescription_impl(),
null, null).getJCas();
jcas.setDocumentText("This is a test.");
try {
//this should throw an exception
jcas.getType(Sentence.type);
fail();
} catch(CASRuntimeException e) {
}
//check that this does not leave JCAS in an inconsistent state
Iterator iter = jcas.getAnnotationIndex().iterator();
assertTrue(iter.hasNext());
Annotation annot = (Annotation)iter.next();
}
Running this gives a ClassCastException trying to cast the result of
iter.next() to an Annotation
