Sebb created HTTPCORE-363:
-----------------------------

             Summary: Unnecessary call to isOpen() before calling close
                 Key: HTTPCORE-363
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-363
             Project: HttpComponents HttpCore
          Issue Type: Improvement
            Reporter: Sebb
            Priority: Minor


There are some instances of the following code:

final Channel channel = this.key.channel();
if (channel.isOpen()) {
    try {
        channel.close();
    } catch (final IOException ignore) {}
}

Eclipse generates a warning that the channel might not be closed.
Obviously that is a false positive, but why bother checking the state?
Surely channel.close() can be repeated without harm?
