Hibernate Query Timeout Bug

The following application replicates https://hibernate.atlassian.net/browse/HHH-16062.

Summary

Queries created from a CriteriaQuery do not have jakarta.persistence.query.timeout values applied.

Steps to replicate

• Install or use Docker to get MySQL running locally on port 3306 with a root user and no password.

• Run schema.sql to create a test database

• Run the Application class a notice the output [test_1, test_2, test_3]

• Run the following SQL commands to lock the tables:

LOCK TABLES test_table READ;
LOCK TABLES test_table WRITE;

• Run the Application class and the application hangs

• Kill the application

• Checkout the hibernate5 branch

• Run the Application class and notice that the expected timeout exception is thrown
