Hello, JBossManagedConnectionPool is behaving differently between 3.2.6 and 4.0.2.
I have an application that is using MySQL streaming result sets. The MySQL version is 4.0.20a and the Connector/J version is 3.1.6. In some cases I have embedded queries. In other words, I scroll through the first result set and, for each row, perform another query that also returns a streaming result set. When performing this second (embedded) query, the DataSource is asked for a connection. In JBoss 3.2.6 it gives me a new connection, i.e. not the one associated with the outer result set. In JBoss 4.0.2 it gives me the same connection [getUnderlyingConnection() was used to determine this]. Because MySQL stipulates you cannot have more than one streaming result set in use on the same connection, the code fails on JBoss version 4.0.2. I thought that maybe class implementing ManagedConnectionPool had changed between the versions, but it appears to be JBossManagedConnectionPool in both cases. So perhaps the code has changed between the versions - but on looking at JBossManagedConnectionPool.java, it is the same in both 3.2.6 and 4.0.2, apart from one very small unrelated change. InternalManagedConnectionPool.java are also the same in both versions. In both 3.2.6 and 4.0.2, the sub-pool being used is PoolBySubject. Could someone please tell me why therefore I am seeing the different behaviour between JBoss 3.2.6 and 4.0.2?
