/**
 * Test for JBERET-231/JBEAP-4811.
 * When a batch job fails due to transaction timeout, another job should be able to run on the same thread.
 * <p>
 * {@link ThreadBatchSetup} configures jberet to have {@code max-threads} 3.
 * The test job, {@code timeout-job.xml}, contains a step with 2 partitions.
 * The test starts the job twice: first with a {@code job.timeout} value to trigger transaction timeout
 * and job execution failure; second time without causing transaction timeout.
 * <p>
 * The first job execution is expected to fail due to transaction timeout.
 * The second job execution should complete successfully.
