Class Waiter

java.lang.Object

org.hsqldb.test.Waiter

public class Waiter
extends java.lang.Object

Single-use synchronization object. Design would be more scalable if there were a separate collection class, instead of the static Waiter.map. The limitation is acceptable since there's no use case for running multiple Test Runners simultaneously from a single JVM (one Test runner can handle multiple test scripts simultaneously or synchronously). (It would be much work to make the collection non-static, because that would require a refactor of TestUtil with proper OOD).
