[Ray Chen]

Hi Martin,
Thank you for your patch!

Is that possible to give a test case to show the problem clearly?

Thanks!

Patch fixing the issue

SocketOutputStream doesn't handle short writes properly
-------------------------------------------------------
Key: HARMONY-6682
URL: https://issues.apache.org/jira/browse/HARMONY-6682
Project: Harmony
Issue Type: Bug
Components: Classlib
Environment: Tested/noticed on Android, same issue identified in

the Harmony code base, too

Reporter: Martin Storsjö
Attachments: outputstream-shortwrite.patch
Even blocking writes can return before the full amount is written, e.g.

if a signal is received, or for any other arbitrary reason.

The java.io.OutputStream.write() interface that SocketOutputStream

implements returns void, and cannot report short writes to the caller, and
therefore is required to loop to retry writing until everything is written,
or until writing fails.

The same issue is reported to Android at
