Hello,

I'm migrating from Fuse ESB 4.4.1 to Fuse ESB Enterprise 7.0.2.fuse-097 (Camel 2.8.0-fuse-06-11 to Camel 2.9.0.fuse-70-097 and I have the following issue with an existing route that fails starting-up:

-

Caused by: org.apache.camel.FailedToCreateRouteException: Failed to create route

There must have been a change in the DSL but the above SimpleIllegalSyntaxException won't tell me where. I'm surprise that a route that compiles won't start (I'm using the Java DSL only).

On top of the stacktrace I have this:

-

]

<<< in route: Route[[From[ref:opus-admin-jms-src]|http://fusesource.com/forums/] -> [OnException[[class ... b

ecause of Unary operator -- has no left hand side token at location 0

My route looks like this:

from("ref:opus-admin-jms-src")

          .routeId("opus-admin-route")

          .process(new CreateLogContextProcessor(Constants.LOG_BUNDLE_FILE_NAME))

          .log(LoggingLevel.INFO, "Operation ${in.header.operationName}() received by the Database Writer component on the opus admin JMS queue.")

            .choice()

              .when(header(Constants.OPERATION_NAME).isEqualTo("createOpus")).beanRef("opusProcessor", "createOpus")

              .when(header(Constants.OPERATION_NAME).isEqualTo("createOpusGroup")).beanRef("opusProcessor", "createOpusGroup")

            .otherwise()

              .log(LoggingLevel.ERROR, "Unknown Operation called : ${in.header.operationName}() !!!")

              .to("ref:error-requests-dir")

            .end();

I'm currently trying to comment-out part of the route in order to pinpoint what's wrong but I can't find out.
