HHH-19280: reproducer

[victornoel]

Here is a reproducer for https://hibernate.atlassian.net/browse/HHH-19280.

The issue is when the DataSource used in MyConnectionProvider is wrapped with the OpenTelemetry JDBC instrumenter. I decided to reuse the ConnectionProvider implementation from Hikari just because I didn't know how to do something simpler, but the problem has nothing to do with Hikari.

Note the debug logs in the log4j file, executing the test will print:

2025-03-26 10:21:45 DEBUG ResourceRegistryStandardImpl:202 - Exception clearing maxRows/queryTimeout [The object is already closed [90007-232]]

The reason why we see this and why it's a problem is explained here: https://hibernate.atlassian.net/browse/HHH-19280?focusedCommentId=119939

to the class?
Thanks

I can but actually is this correct? it's a copy paste of HikariCPConnectionProvider which have:

 * See the lgpl.txt file in the root directory or <http://www.gnu.org/licenses/lgpl-2.1.html>.
 */

Also, ideally, if you know of a way to do without hikaricp, it would be even better :) is there some idiomatic way of wrapping the DataSource used in the tests without implementing my own ConnectionProvider for example?

ok I'll try to figure it out. Thanks again for the reproducer.
