Key Optimizations
Separation of Concerns
Created a separate PriorityRunnableComparator class to handle the comparison logic. This improves readability and maintains a single responsibility principle.
Improved Latch Handling
Introduced a dedicated method awaitPauseLatch() for clarity in the beforeExecute method. This encapsulates the waiting logic and enhances readability.
Interrupt Handling
When an InterruptedException occurs in the awaitPauseLatch method, the interrupt status is restored with Thread.currentThread().interrupt(). This is crucial for proper thread interruption handling.
Simplified Logic
Used Integer.compare() for comparing priorities in the comparator. This is more concise and avoids manual subtraction.
