package org.apache.pulsar.websocket.stats;
+import static io.netty.util.internal.PlatformDependent.maxDirectMemory;
Review comment:
This import is illegal based on the rules:
```
➜ sn-pulsar git:(neng/pulsar-module-checkstyle) mvn checkstyle:check
-Dpulsar.basedir=. -pl pulsar-websocket
...
[ERROR]
src/main/java/org/apache/pulsar/websocket/stats/JvmMetrics.java:[21,1]
(imports) IllegalImport: Illegal import -
io.netty.util.internal.PlatformDependent.maxDirectMemory.
```
But I don't have a good idea on how to fix this one. Need some help on it.
