Message headers are converted to lower-case when a SwitchYard service is invoked in a CamelRoute like:

from("switchyard://DummyInterface")

   .setHeader("x.UPPERCASEHEADER").constant("test")

   .to("switchyard://DummyInterfaceRuleService?operationName=invoke")

   .log("Upper-case: ${header[UPPERCASEHEADER]}")

   .log("Lower-case: ${header[uppercaseheader]}");

[code}

The resulting output is

14:30:30,024 INFO [route1] Upper-case:
14:30:30,024 INFO [route1] Lower-case: test

and not

14:30:30,024 INFO [route1] Upper-case: test
14:30:30,024 INFO [route1] Lower-case:

as expected.

The bug seems to be related to #
