Description

When writing the following code, the expression

${headers.true} == ${headers.true}

evaluates to false - rather than the expected true.

    <camelContext trace="false" xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="direct:entry"/>

            <setHeader headerName="true">
                <constant>true</constant>
            </setHeader>

            <setBody>
                <simple resultType="java.lang.Boolean">${headers.true} == ${headers.true}</simple>
            </setBody>

            <log message="The expression evaluated to :: ${body}" />

        </route>
    </camelContext>

[                          main] route1                         INFO  The expression evaluated to :: false

Edit: I have tried debugging this, and it seems that the "==" token is being treated as a LiteralExpression - rather than an being a Binary Operator? I'm imaging therefore that the `false` is purely from coercing a String to the java.lang.Boolean resultType?
