Clarification about ClosedFileSystemException

[Francis Galiegue]

Hello,

The javadoc says:

    Unchecked exception thrown when an attempt is made to invoke an
operation on a file and the file system is closed

So, what it means that an operation is "made on a file"? What happens
if, for instance, I have a FileSystem instance which is closed and I
attempt to call, say, .newWatchService() on it? A FileSystem is not a
file...
