Example 51 with DefaultHttpResponse

use of org.jboss.netty.handler.codec.http.DefaultHttpResponse in project cdap by caskdata.

the class HttpRequestHandler method exceptionCaught.

@Override

    Throwable cause = e.getCause();

    switch(exceptionsHandled.incrementAndGet()) {

            // if this is the first error, break and handle the error normally (below)
            break;
        case 2:
            // if its the second time, log and return
            LOG.error("Not handling exception due to already having handled an exception in Request Handler {}", ctx.getChannel(), cause);
        // fall through
        default:
            // in an exception and cause recursion
            return;
