Motivation:
The behaviour of the FixedChannelPool.release was inconsistent with the
SimpleChannelPool implementation, in that given promise is returned.
In the FixedChannelPool implementation a new promise was return and
this meant that the completion of that promise can be different.
Specifically on releasing a channel to a closed pool, the parameter
promise is failed with an IllegalStateException but the returned one
will have been successful (as it was completed by call to super
.release)
Modification:
Return the given promise as the result of FixedChannelPool.release
Result:
Returned promise will reflect the result of the release operation.
If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
