Cannot expand a template which contains colon in one of its query param

[sandeep14-singh]

Lets say, we have a template = https://someUrl{?someQuery:Param} where the we have a query param which has colon in it = "someQuery:Param"
If i try to expand this via :

Map<String, Object> templateParams = new HashMap<>();
templateParams.put("someQuery:Param", "hello");
UriTemplate
          .fromTemplate("https://someUrl{?someQuery:Param}").expand(templateParams);

It fails with -
com.damnhandy.uri.template.MalformedUriTemplateException: The prefix value for repo was not a number

Is there a way to escape colon (:) if query param contains it ?
