--------------------------------------

             Summary: EndpointDSL breaks expressions in query parameters
                 Key: CAMEL-15455
                 URL: https://issues.apache.org/jira/browse/CAMEL-15455
             Project: Camel
          Issue Type: Bug
          Components: camel-endpointdsl
    Affects Versions: 3.4.3
            Reporter: Vladimir Dobos


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}
