------------------------------------------
Summary: SSLIOSession state can get out of sync with underlying IOSession state
Key: HTTPCORE-298
URL:
https://issues.apache.org/jira/browse/HTTPCORE-298 Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore NIO
Affects Versions: 4.1.4
Environment: observed on Ubuntu 10.0.4, but I think it could happen anywhere
Reporter: Sandeep Tamhankar
Under heavy load, I've observed my application call SSLIOSession.isClosed() to decide if the connection can be reused for a pending outbound request. It returns false. However, the underlying IOSessionImpl is actually closed. I believe that AbstractIOReactor also holds a reference to that underlying IOSession and it can be independently closed from that end.
My proposed fix is simple (and very non-invasive, but possibly not correct in that I don't have the SSLIOSession update its state upon discovering that the underlying IOSession is closed): update SSLIOSession.isClosed as followed:
public boolean isClosed() {
return this.status >= CLOSING || this.session.isClosed();
}
