Hi,
I am running into some sort of race condition when calling unBind(). I am not
sure exactly why but this simple test case demonstrates the issue:
@Test
public void testRebind() throws Exception
{
LdapConnection connection = pool.getConnection();
try
{
for ( int i = 0; i < 1000; i++ ) {
connection.unBind();
connection.bind(
ServerDNConstants.ADMIN_SYSTEM_DN,
"secret" );
}
}
finally
{
assertNotNull( connection );
pool.releaseConnection( connection );
}
}
It will fail at some point in the loop (usually around 100, but I have seen 10
or even 350). The exception is usually:
java.lang.IllegalStateException: The connector has been disposed.

Though it occasionally fails with a NullPointerException on the connector
object inside of bind() method at connector.connect(). In my opinion, this is
clearly a bug, but wanted input before filing it. Does anybody have any info
that may pertain? Also, I notice that unBind() actually closes the session.
Why is this? It seems like that is a bad idea as I don't see any way to
unBind() and keep the session live. Does anybody know if there is a good
reason why unBind() closes the session? Any argument against overloading
unBind() to take an boolean to closeSession?
Thank You,
