This is caused primarily by the fact that the temp files or the classpath files in the agent home are corrupted.
Resolution
Try the following suggestions in steps:
(Only applicable to Bamboo Server) Restart the Bamboo server
Restart the remote agent host
If the above two steps have not fixed the issue, delete the agent home and reinstall the remote agents
If the issue still persists, investigate for any corrupted files on the Bamboo Server as the Remote Agent will always synchronize its files from the Server
