You should always be releasing the connection back to the connection pool.
This means you should have a finally statement on your try/catch so that it
is always released. Then you shouldn't have this problem when an exception
occurs. In terms of the connection pool I'm using, you also have a maximum
number you allocate as well as a minimum, so it will automatically get a new
connection for you - up to the max. At some point, however, you will run out
unless you free the connection, so be careful to always do that, even when
an exception occurs.
