. . .
Are you going to update the patch to only use this path when the SocketChannel is configured blocking?
Yes, we will post a new webrev when we have changed the code to only apply to blocking sockets.

Here is the new webrev.
https://openjdkcontrib.blob.core.windows.net/transferto/webrev-20141105.zip

We also tried to apply what we learned from the previous submission, so this one uses "jdk.net.enableFastFileTransfer" as the setting name, allows -Djdk.net.enableFastFileTransfer to enable the setting and adds a test that uses the setting.

Thanks,
Kirk
