Brief change log

Fixes Implemented:

The following fixes have been implemented:

1. Modified the completeTask method (lines 565-577):

• First, call taskRuntime.complete() (acquire and release the database lock).
• After the database lock is released, acquire TableOptimizingProcess.this.lock and call acceptResult.
• Ensure the lock acquisition order is consistent: acquire TableOptimizingProcess.this.lock first, then acquire the database lock.

2. Removed the whenCompleted callback registration (lines 910-922 and 932-945):

• Avoid synchronously calling acceptResult while holding the database lock.
• Instead, explicitly call acceptResult within completeTask.

3. Modified the cancelTasks method (lines 897-902):

• First, cancel all tasks (acquire and release the database lock).

• Then call acceptResult for each canceled task (while holding TableOptimizingProcess.this.lock).
