Symptoms

When using version 21.1 of UCP, there is a discrepancy in what gets returned for getConnectionsClosedCount() in cases where the number of connections borrowed from the pool never exceeds the pool's specific minPoolSize.

Specifically, given a scenario where an application does not borrow all of the connections from the connection pool before returning them:  

For 18c and 19c UCP, there is no growth in the number returned from the method call getConnectionsClosedCount().  The number returned remains at zero.

However, in UCP 21.1, the returned number from getConnectionsClosedCount() is a nonzero value that increases over time.
