Missing break statement in switch case

## Description

SonarCloud reports a violation of rule `java:S128` , A case block in the switch statement does not end with a `break`, `return`, or `throw`. This can cause the execution to continue into the next case unintentionally.

## How to fix
To fix this, add a `break` at the end of the case block.

## Example
```tsx
case HANDSHAKE_DATANODE_V1:{
try {
......
} finally {
..........
}
break;
}
```
