Tiago R. Espinha commented on DERBY-4310:
-----------------------------------------
Interestingly enough I got that same failure on rerun. This becomes more
intriguing considering the fact that it was I who introduced that file I
believe. I'm thinking something might be wrong with my code tree. The plot
thickens.
I'm not sure we would need this for the BrokeredStatement. After all, if this
isn't a prepared statement, when we duplicate the statement to accommodate the
connection change the statement does not get reprepared, so nothing evil should
happen. However, perhaps for standardization's sake we should have all the
statements being closed in the same manner (this would also possibly improve
performance? We don't really need to duplicate a statement to close it...).
As for the remaining calls, yes, we should probably get this for isClosed() and
for isValid() as these are the other two methods that throw an exception when
the statement is closed according to ClosedObjectTest.
--------------8<------------------
if (name.equals("close") || name.equals("isClosed")
|| name.equals("isValid")) {
return false;
}
-------------8<--------------------
Still, looking at BrokeredStatement's implementation of isClosed(), I am
dazzled. Why exactly do we have an exception being thrown there?

> The XATest is showing the following on the log:
> 2009-07-16 00:15:42.838 GMT : Apache Derby Network Server - 10.6.0.0 alpha -
> (794457M) started and ready to accept connections on port 9920
> 2009-07-16 00:15:44.394 GMT : Unexpected exception:
> Table/View 'APP.FOO' does not exist.
> Here is the full stack trace from derby.log. The error comes closing a
> prepared statement on a brokered connection if the table referenced by the
> statement has been dropped. This looks like an embedded bug causing network
> server shutdown to fail. Also if this test is enabled in a suite DERBY-4155,
> the next time network server is started the tests will hang with
> java.net.BindException: Address already in use: NET_Bind in the derby.log
