I've stumbled on an issue where ObservableElementList can cause an
IndexOutOfBoundsException in java.util.ArrayList when switching to multi
listener mode.

There are two conditions:
- the Connector is smart enough to skip over some elements and attach a listener
to others
- but not smart enough to re-use the same listener object for each element it
attaches to

The exception is consistently thrown when adding the second element that the
Connector attaches a listener to, but only if there are elements in the list
which were skipped over.

I will attach a JUnit test that demonstrates the problem.

Perfect bug report and test case. It made the problem easy to find and a smaller
reproducing test case easy to write.

In the end, the problem was that my logic for switching from "single listener
mode" to "multi listener mode" sort of assumed that the Connector was *always*
installing an EventListener, when that need not be the case.

The latest GL jars contain the fix now.
