Using AutoCloseable doesn't compile and I am stuck:

[dr0i]

Following #667 (review):
Using AutoCloseable doesn't compile and I am stuck:

Compiles with an error:

AbstractReadOnlyMap.java:32: warning: [try] auto-closeable resource AbstractReadOnlyMap<K,V> has a member method close() that could throw InterruptedException
    public abstract class AbstractReadOnlyMap<K, V> implements Map<K, V>, AutoCloseable {
                    ^
      where K,V are type-variables:
        K extends Object declared in class AbstractReadOnlyMap
        V extends Object declared in class AbstractReadOnlyMap

See #666.

But this also appears to support my second point:

I don't understand what you are pasting. diff $fileA $fileA ? What files are these?

[blackwinter]

I don't understand your confusion... The paths are right there. It's just the output of git diff.
