    Description

      Background in JDK-8260486, and discussion in https://mail.openjdk.java.net/pipermail/nio-dev/2021-January/008094.html

      The proposal is to add a note to the transferFrom API docs to make it clearer a returning value of 0, meaning no bytes available, is ambiguous when the source channel is configured non-blocking. It could mean the source channel is at EOF or could mean that there are just no bytes available without blocking.
