IndexOutOfBoundsException in org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1720) - Mailing list pgsql-jdbc

Hi, I noticed a strange Exception on my test server using
postgresql-9.0-801.jdbc4 in this code fragment:

QueryExecutorImpl.java:1720 (pendingBindQueue#get(int))
----------
case '2':    // Bind Complete  (response to Bind)
                pgStream.ReceiveInteger4(); // len, discarded
                Portal boundPortal =
(Portal)pendingBindQueue.get(bindIndex++);
                if (logger.logDebug())
                    logger.debug(" <=BE BindComplete [" + boundPortal +
"]");
                registerOpenPortal(boundPortal);
                break;
----------

I haven't manged to reproduce this issue on my dev machine. But can someone
give me a hint what happens here? What is a Portal and what does it mean if
an IndexOutOfBounds Exception occurs here?


Thanks,

Jan
