Open-source project
BackPorch ShedLock
A Java 6 and 7 backport of ShedLock for coordinating scheduled tasks across application nodes.
BackPorch ShedLock brings the core distributed-locking behavior of ShedLock to applications that remain on Java 6 or 7. It prevents equivalent scheduled tasks from running concurrently across nodes by coordinating through JDBC or Hazelcast-backed locks.
Status
This repository is preserved as a portfolio artifact and reference implementation. I do not actively maintain it, review dependency updates, or provide support for production use.
New projects and applications on Java 8 or newer should use the upstream ShedLock library instead.
Why it exists
The project addressed a constrained runtime requirement without requiring a broader scheduler replacement. It demonstrates a pragmatic approach to extending useful open-source behavior into environments that could not yet adopt the current upstream library.
