It would be good to include a bit more context in the PR description regarding the motivation. I assume it's noisy and doesn't add useful information. |
SG, will add a description in the commit message. |

Although the lock exception log is at the DEBUG level only, many people were confused with stack traces that something serious happened; plus, in the source code there is only one call path that can lead to the capture of LockException at task manager/stream thread, so even for debugging purposes there’s no extra information we can get from anyways.
