Camel 2.9.0 -- StackOverflowError initializing route with otherwise() clause

[ilopanj]

Hi,

I'm preparing to upgrade an application to 2.9.0 from 2.8.3 and found a
problem initializing one of our existing routes defined with the Java DSL:

from ("direct:outerRoute")
                .choice ()
                    .when(header("test-header").isNotNull())
                        .to("direct:mainProcess")
                    .otherwise ()
                        .to ("log:badMessage")
                        .transform ()
                                .method (rejectBean, "processRejectedMessage")
                 .end ();

I get a StackOverflowError initializing the route when using version 2.9.0
in the staging repo, but it works fine with version 2.8.3.  Here's a snippet
of the error below:

Exception in thread "SpringOsgiExtenderThread-27"

... etc ...

I can work around the problem by factoring the otherwise() portion into a
separate route:

from ("direct:handleBadMessage")
    .to ("log:badMessage")
    .transform ()
        .method (rejectBean, "processRejectedMessage");

from ("direct:outerRoute")
                .choice ()
                    .when(header("test-header").isNotNull())
                        .to("direct:mainProcess")
                    .otherwise ()
                        .to("direct:handleBadMessage")
                 .end ();

Thanks,
Jerry
