Description Bruno Koeferli CLA 2011-06-14 04:58:43 EDT 
Created attachment 197943 [details]
exceptions on client disconnect (it seems to me that the second exception is a subsequent fault)

Build Identifier: 3.7.0.201106071621, Build id: 20110607-1621

Client disconnects causes some exceptions in "ServiceTunnelServlet.doPost" (see attachment). The comments in the catch-block state that these exceptions should be ignored, but they don't.

Reproducible: Always

Steps to Reproduce:
1. Browse a LookupCall-SmartField (a longer taking call suits best)
2. Click the SmartField-DropDown away (which closes the connection)
3. Voilà, you can find the exceptions in the server log

      //ignore disconnect errors
      // we don't want to throw an exception, if the client closed the connection
      Throwable cause = t;
      while (cause != null) {
        if (cause instanceof SocketException) {
          return;
        }
        else if (cause.getClass().getSimpleName().equalsIgnoreCase("EofException")) {
          return;
        }
        else if (cause instanceof InterruptedIOException) {
          return;
        }
        // next
        cause = cause.getCause();
      }
