Running without GriefPrevention

  • I attempted running the server without GriefPrevention installed.
  • The problem does not occur when GriefPrevention is removed from the server.

Running with only GriefPrevention

  • I attempted running only GriefPrevention on the server.
  • The issue still occurs when GriefPrevention is the only plugin running.

Running on a fresh, clean server installation

  • I attempted testing for the issue on a new server.
  • The issue still occurs on a new server.

Using unmodified client

  • I attempted testing for the issue with the vanilla client.
  • The issue still occurs when using the vanilla client.

We appreciate you taking the time to fill out a bug report!

  • I searched for similar issues before submitting this bug report.

This is an issue with either your playerdata or the server's datafixers and can't be fixed by GP. If you can reproduce this consistently, you should report it to Spigot and send them a sample player file.

/e: You could also configure Log4J to ignore these errors.

For clarity, the logging is done by the datafixer during loading, but as the server returns the value as normal, GP has no idea anything is "wrong" internally. This really isn't something GP can address without just not assembling last playtimes.

If I understand what Jikoo mentioned correctly, this is an issue with the server's playerdata files (found in default world > playerdata), not GP's. Thus a craftbukkit/spigot error when calling OfflinePlayer#getLastPlayed.
