      Steps to reproduce from scratch:

      A) Unzip last Fuse 6.3.0 media 'jboss-fuse-karaf-6.3.0.redhat-424.zip'
      B) Install quickstart

      1. cd $FUSE_HOME
      2. cd quickstarts/cxf/rest
      3. mvn install

      C) Set up a fresh instance of jboss fuse 6.3.0 with both an http gateway container and another separate container running this cxf quickstart bundle

      1. Uncomment 'admin' user from 'etc/users.properties' (not really needed I guess)
      2. Start via 'bin/fuse'
      3. fabric:create --wait-for-provisioning --manual-ip localhost --resolver manualip --zookeeper-password admin
      4. container-create-child --profile gateway-http root gateway
      5. container-create-child --profile feature-cxf root test
      7. container-connect test
      8. osgi:install -s mvn:org.jboss.quickstarts.fuse/cxf-rest/6.3.0.redhat-424

      D) Invoke web service with illegal parameters

      $ curl "http://localhost:9000/cxf/crm/customerservice/customers/123?foo=bar|baz"

      The request to the gateway url results in exceptions on the gateway container and the request, from the perspective of the client, hangs indefinitely.

      Check gateway container logs under 'instances/gateway/data/log/fuse.log'.

    Description

      When sending an URL with some invalid characters to a fabric gateway, the gateway container logs a NullPointerException, and the client hangs

      Please see attached "NPE-gateway.txt" file, for the full exception stack trace

      If the same URL is sent directly to the container that host the web service presented by the gateway, the client gets a response

      Sample client and URL used:

      $ curl "http://localhost:8183/cxf/crm/customerservice/customers/123?foo=bar|baz"

      Probably the same behavior could happen with other special characters

          Feature Request - Feature requests from customers and/or users ENTESB-12871 Fabric Gateway should have same behavior on CXF web services, when handling illegal not encoded characters on URL

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
