Motivation:
- A `HttpPostMultipartRequestDecoder` contains two pairs of the same methods: `readFileUploadByteMultipartStandard`+`readFileUploadByteMultipart` and `loadFieldMultipartStandard`+`loadFieldMultipart`.
- These methods use `NotEnoughDataDecoderException` to detecting not last data chunk (exception handling is very expensive).
- These methods can be greatly simplified.
- Methods `loadFieldMultipart` and `loadFieldMultipartStandard` has an unnecessary catching for the `IndexOutOfBoundsException`.
Modifications:
- Remove duplicate methods.
- Replace handling `NotEnoughDataDecoderException` by the return of a boolean result.
- Simplify code.
Result:
The code is cleaner and easier to support. Less exception handling logic.
