## Issue Evaluation **Type:** Enhancement **Category:** Performance - Memory Allocation **Priority:** Medium ### Assessment Well-documented performance issue based on JFR profiling. The analysis is precise and the proposed fixes are straightforward. ### Analysis 1. **getProperty()**: Creates unnecessary empty HashMap when properties is null - common on producer send path 2. **getPriority()**: Throws ~16,000 NFE/min when PRIORITY is unset (majority of messages) ### Proposed Fix Review - Return null immediately when properties is null (read-only method should not mutate state) - Add null/empty fast-path in getPriority() before calling NumberUtils.toInt() ### Verdict ✅ **Accepted** - This is a valid performance optimization that eliminates unnecessary allocations and exception overhead on the hot path. JFR profiling data supports the impact assessment. --- *🤖 Automated evaluation by oss-sentinel-ai* -- This is an automated message from the Apache Git Service.
