ImsCwbReader.hasNext() switches to next CAS

[GoogleCodeExporter]

Repeatedly calling ImsCwbReader.hasNext() has the effect of skipping through 
the complete input, even if getNext() is never called.

I cannot reproduce this issue. Do you have an example test for that?

Try something like this:

JCasIterator i = SimplePipeline.iteratePipeline(imscwbreader).iterator();

while (i.hasNext()) {
  // do nothing
}

Normally, this loop should not terminate, because i.next() is never called. 
However, in my experience, it terminates.

Tried that, it does not terminate for me after waiting a resonable amount of 
time (2 minutes for a 200kb file). I also tried:

JCasIterator i = SimplePipeline.iteratePipeline(imscwbreader).iterator();

int c = 0;
while (i.hasNext()) {
  c++;
  if (c == 3 || c == 100) {
    System.out.println(i.next().getDocumentText());
  }
}

It prints the first text in the file, then the second, both as expected.
Do you have an example test file, or a concrete application where this happens?

I had such a case, but I "fixed" it ;) I'll try to set one up again.

Well, if you call "next", then it terminates. But repeatedly calling hasNext() 
without calling next() also terminated for me, but it shouldn't!

The point was, hasNext() did not advance the iterator in my test. Also, the two 
calls to next() did expectedly not have any impact on the non-termination of my 
test, as the test-file has more than 2 texts.

Cannot reproduce it either. Looks like I misinterpreted my code and drew false 
conclusions. Sorry for the confusion.
