> datasources.SharedPoolDataSource.getPooledConnectionAndInfo() contains an impossible
null check:
> {code}
> synchronized (userKeys) {
>     key = getUserPassKey(username, password);
> }
>         
> try {
>     info = (PooledConnectionAndInfo) pool.borrowObject(key);
> }
> catch (SQLException ex) {  // Remove bad UserPassKey
>     if (userKeys != null) { // <== cannot be null here, else synch. would have failed
with NPE
> ...
> {code}
> The null check should be removed, as userKeys cannot be null (it is a final variable,
and set non-null).
