Hello,
Using embedded Jetty. jetty-home-10.0.11.
I have a problem with stopping and destroying and restarting a HttpClient.
When stopping an internal component MessagingGatewayFacebook embedding an
HttpClient instance, it calls closeHttpClient(). When needing to start the
component from a jetty servlet, it calls createHttpClient().
private HttpClient httpClient;
private void createHttpClient() {
try {
if (httpClient == null) {
SslContextFactory.Client
sslContextFactory = new SslContextFactory.Client(true);
ClientConnector
clientConnector = new ClientConnector();
clientConnector.setSslContextFactory(sslContextFactory);
httpClient = new
HttpClient(new HttpClientTransportDynamic(clientConnector));
httpClient.start();
logger.debug("HttpClient " +
httpClient + " started");
}
httpClient.setConnectTimeout(.);
httpClient.setIdleTimeout(.);
} catch (Exception ex) {
logger.error("HttpClient " + httpClient + "
cannot be started", ex);
httpClient = null;
}
}
private void closeHttpClient() {
if (httpClient != null) {
try {
httpClient.stop();
httpClient.destroy();
logger.debug("HttpClient " +
httpClient + " stopped");
} catch (Exception ex) {
logger.debug("HttpClient " +
httpClient + " cannot be stopped", ex);
}
httpClient = null;
}
}
closeHttpClient() sets the httpClient to null after stop+destroy on the
client.
createHttpClient() creates a new HttpClient.
Sometimes (it is not always the case), we get this exception on
httpClient.start() showing that the AbstractConnectorHttpClientTransport
cannot be started since it has been destroyed !

I may do something wrong but I don't see where.
Thank you to give a help.
