Hi,

I have a question about the AutoCloseable interface. Since I cannot find any mention about how asynchronously closeable resources should be handled.

Say I wanted juc.ThreadPoolExecutorService to implement AutoCloseable. When close() returned should the executor be in the shutdown phase or in the terminated phase?

In other words should I implement close() like this (which I believe)

public void close() { executor.shutdown(); executor.awaitTermination(Long.MAX_VALUE, TimeUnit.SECONDS); //ignore any interrupted exceptions }

or like this

public void close() { executor.shutdown(); }
