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.
