URL: https://github.com/apache/rocketmq/issues/3533
**BUG REPORT**
1. Please describe the issue you observed:
When initializing a HashMap as a local variable that will not escape, it
is better to specify the `initialCapacity`.
The code in class
`org.apache.rocketmq.broker.filter.MessageEvaluationContext#keyValues` shown
below is better.
```java
public Map<String, Object> keyValues() {
if (properties == null) {
return null;
}
Map<String, Object> copy = new HashMap<String,
Object>(properties.size(), 1);
for (String key : properties.keySet()) {
copy.put(key, properties.get(key));
}
return copy;
}
```
2. Please tell us about your environment:
