    Constant Field Values
  - ZONE_ID_SYSTEM
```
public static final ZoneId ZONE_ID_SYSTEM
```
    Specifies the zone id used by the access log
  - PREDICATE_GROUP_FLUSH
```

```
- Method Detail
  - safeRelease
```
public static void safeRelease(Object msg)
```
    Try to call ReferenceCounted.release() if the specified message implements ReferenceCounted. If the specified message doesn't implement ReferenceCounted or it is already released, this method does nothing.

```
@Deprecated
public static String toPrettyHexDump(Object msg)
```
    Deprecated. as of 1.1.0. This will be removed in 2.0.0 as the functionality is not used anymore.
