I wonder though whether TPE.finalize() is ever actually hit in practice: TPE is (by definition) a thread pool, and every live thread in that pool has (by way of TPE.Worker) a strong reference to the TPE itself via an outer class reference which is passed around in enough places to make me think that it would never actually be collectable in a real-world situation, unless all core threads were allowed to time out. -- - DML
