Description dynamite 2004-03-01 15:35:31 UTC

I am using the latest QA build (25th Feb 2004) and
Oracle 8.1.7. Often, but not always, when reading
a table of data via the 'View data...' menu item,
I get the exception given below. It is fairly
harmless as I actually receive all the data in the
table. It is not clear to me why sometimes I don't
get the exception other than when the exception
seems to occur most often when a query is first run.

Comment 1 Jiri Skrivanek 2004-03-02 11:48:53 UTC

I cannot reproduce it. What JDK do you use? What driver? How many
columns, rows does your table have?

Comment 2 dynamite 2004-03-02 15:07:22 UTC

The JDBC driver is that which comes with Oracle 9.0.1.
JDK version is 1.5.0-beta.

It is also worth pointing out that my activities through NetBeans
included updating tables as well as simply selecting data.

This doesn't seem an easy one to find. I have no reliable steps to
reproduce the problem other than a suspicion that it may be machine
load related.

Comment 3 Jiri Skrivanek 2004-03-03 08:59:25 UTC

Even with JDK1.5.0 I am not able to reproduce it. Because the
exception doesn't come from NetBeans source code, it is not easy to
track what's wrong. If you find a scenario, how to reproduce, it will
be helpful.

Comment 4 Jiri Skrivanek 2004-03-11 17:17:26 UTC

Resolving as worksforme. If you are able to reproduce it, feel free to
reopen.
