>             Project: Camel
>          Issue Type: Bug
>          Components: camel-endpointdsl
>    Affects Versions: 3.4.3
>            Reporter: Vladimir Dobos
>            Assignee: Claus Ibsen
>            Priority: Minor
>             Fix For: 3.5.0, 3.4.4

> Expressions in parameters are destroyed by url-encoding during url creation in AbstractEndpointBuilder (using little non-sensical example to make reproduction setup easier).
> For example:
> {code:java}
> .toD(seda("someName").size("${header.size}")){code}
> will be translated by AbstractEndpointBuilder#computeUri (which uses URISupport#createQueryString) to
> _seda://someName?size=%24%7Bheader.size%7D_
> This will, of course, throw exception on endpoint creation.
> For some reason, thrown exception is url-decoded, so parameter names will look OK, even when they are broken (this makes the error more difficult to spot)
> {code:java}
> ...
> java.lang.String to the required type: int with value ${header.size} due to org.apache.camel.TypeConversionException: Error during type conversion from type: java.lang.String to the required type: java.lang.Integer with value ${header.size} due to java.lang.NumberFormatException: For input string: "${header.size}"
> ...
> {code}
> Enclosing expressions in RAW(..), fixes the issue, it is however quite suboptimal.
> Following workaround will work:
> {code:java}
> .toD(seda("someName").size("RAW(${header.size})")){code}
>
