public class st_derby715
extends BaseTest

The purpose of this test is to reproduce JIRA DERBY-715: Sometimes a deadlock would be incorrectly reported as a timeout. The bug seemed to always reproduce at least once if the following test was run (at least one of the iterations in the loop would get an incorrect timeout vs. a deadlock).
