[Fuse Online] Path resolution in REST API call fails to append a portion of the relative URL

Issue

Using Fuse Online an integration is deployed that needs to call an external REST service based on an OpenAPI 2.0 (Swagger) definition.

When trying to resolve the URL path from the given OpenAPI 2.0 document the trailing part of the path after the last path parameter place holder is lost.

For example for a REST endpoint URL with path:
http://myrestendpoint:8080/path/{param}/will/be/lost

it gets resolved as:
http://myrestendpoint:8080/path/{param}

and the trailing URL path /will/be/lost is lost.

As a result the API call fails with an error similar to
org.apache.camel.http.common.HttpOperationFailedException:
HTTP operation failed invoking http://myrestendpoint:8080/path/<resolved-param> with statusCode: 500
