RestEasy Client encodes the path parameters with white chars incorrectly.

RestEasy Client encodes the path parameters with white chars incorrectly.

SCENARIO to reproduce:

1. Using RestEasy Client call a REST method with a path parameter. Set the value of this path parameter to:
'something something'

2. Display/trace the decoded value of this parameter on the server side.

RESULT: The displayed path parameter on the server side is incorrect and different than the original one.
'something%20something'

EXPECTED RESULT:
The displayed, decoded path parameter should be 'something something'!

SOLUTION:
I found the suspected code in the class: ./resteasy-jaxrs-1-1/resteasy-jaxrs/src/main/java/org/jboss/resteasy/specimpl/UriBuilderImpl.java

ORIGINAL CODE:
//protected StringBuffer replaceParameter(String name, String value, boolean isEncoded, String string, StringBuffer buffer)
//{
// Matcher matcher = PathHelper.URI_PARAM_PATTERN.matcher(string);
// while (matcher.find())
//

{ // String param = matcher.group(1); // if (!param.equals(name)) continue; // value = Encode.encodeSegment(value, false); // if (!isEncoded) value = value.replace("%", "%25"); // else Encode.encodeNonCodes(value); // matcher.appendReplacement(buffer, value); // }

// matcher.appendTail(buffer);
// return buffer;
//}

PROPOSED CODE:
//protected StringBuffer replaceParameter(String name, String value, boolean isEncoded, String string, StringBuffer buffer)
//{
// Matcher matcher = PathHelper.URI_PARAM_PATTERN.matcher(string);
// while (matcher.find())
// {
// String param = matcher.group(1);
// if (!param.equals(name)) continue;
//
// if (!isEncoded)

{ value = value.replace("%", "%25"); // value = Encode.encodeSegment(value, false); // }

// else
// value = Encode.encodeNonCodes(value);
// matcher.appendReplacement(buffer, value);
// }
// matcher.appendTail(buffer);
// return buffer;
//}

The example project containing a simple echo server and test reproducing the problem is attached. It can be build using maven.
