---------------------------------
Summary: OmMultipartPartKeyCodec should not use UTF8.decode(..)
Key: HDDS-15348
URL: https://issues.apache.org/jira/browse/HDDS-15348
Project: Apache Ozone
Issue Type: Bug
Components: OM
Reporter: Tsz-wo Sze
We should use StringCodec since UTF_8.decode(..) below uses
CodingErrorAction.REPLACE. When there is an error, it will silently replace
characters and cause unexpected behavior.
When there is an error, the correct behavior is to throw an exception.
```java
// java.nio.charset.Charset.java
public final CharBuffer decode(ByteBuffer bb) {
try {
return ThreadLocalCoders.decoderFor(this)
.onMalformedInput(CodingErrorAction.REPLACE)
.onUnmappableCharacter(CodingErrorAction.REPLACE)
.decode(bb);
} catch (CharacterCodingException x) {
throw new Error(x); // Can't happen
}
}
```
