Quartz 1.6.2 Release Notes

This release contains a small but important bug fix and one small new feature improvement to the Quartz 1.6.1 release.

See the changelog below for complete details of this release.

Key Changes

  • A bug fix for an exception that can occur in the main scheduler thread when the system is under high load and triggers have missed their fire times
  • Addition of ZeroSizeThreadPool, which may be of some use (to save system resources) for users who create Scheduler instances for the purpose of managing jobs/triggers, but which will never have start() invoked on them.

Core API changes

  • None
