      This error is not written to the log file, only raised on the console.

      Further analysis revealed that the camel-hdfs feature pulls in Jetty 6.1.26_4 (mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.jetty/6.1.26_4) although Jetty 7 is already installed out of the box.
      When the camel-hdfs features triggers an update of bundle mvn:org.ops4j.pax.web/pax-web-jsp/1.0.10 (211), it raises the above error.

      So this error can also be reproduced by this sequence of commands on the karaf shell:

      osgi:install mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.jetty/6.1.26_4
osgi:refresh 211

          is related to

          Bug - A problem that impairs or prevents the functions of the product. ENTESB-233 servicemix-http uses jetty 6 whilest rest of fuse esb uses jetty 7.5.4.v20111024

          • 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.
