Description
Attempting to build the current jdk master on AIX halts at:

* For target jdk_modules_java.base__the.java.base_batch:
/home/hotspot/openjdk/jdk-fork/src/java.base/share/classes/sun/nio/ch/PollerProvider.java:67: error: cannot find symbol
            return new DefaultPollerProvider();
                       ^
  symbol:   class DefaultPollerProvider
  location: class PollerProvider

Possible implementations for DefaultPollerProvider are given by:

- src/java.base/linux/classes/sun/nio/ch/DefaultPollerProvider.java
- src/java.base/macosx/classes/sun/nio/ch/DefaultPollerProvider.java
- src/java.base/windows/classes/sun/nio/ch/DefaultPollerProvider.java
 
However, none of the libraries or kernel modules used (epoll, kqueue, wepoll) by these implementations are available on AIX out of the box.

Richard Reingruber is working to get ppc64 ports to work, see JDK-8286446 and JDK-8286302.

Thanks for the head's up :-)

The Pollset implementation seems to be the most straightforward of the changes required. What is proving more difficult are the calls to 'unimplemented()' and the other assertions added by the change which break the build in subtle ways. These will have to be found and fixed before the project can be built on AIX again.

The port of JEP 425 to AIX will probably need a pollset implementation of Poller.
