Encoding issue with curly brackets and space in UriBuilder

Question

I am using the com.sun.jersey.api.uri.UriBuilderImpl implementation of UriBuilder to encode a URL (version 1.19). The issue arises when the query parameter of my URL includes both curly brackets and a space.

Example:

UriBuilder uriBuilder = fromUri("www.something.com")
        .queryParam("q", "{some thing}");

return uriBuilder.build().toString();

This fails with:

javax.ws.rs.core.UriBuilderException: java.net.URISyntaxException: Illegal character in query at index 27: www.something.com?q=%7Bsome thing%7D

Which is interesting, as if I take the curly brackets away, I get the expected encoding: www.something.com?q=some+thing...

org.apache.http.client.utils.URIBuilder encodes that as I would expect, which is: www.something.com?q=%7Bsome+thing%7D

I've tried doing this:

...
.queryParam("q", UriComponent.encode(searchQuery, UriComponent.Type.QUERY_PARAM)).
.build();

But then the space character also gets encoded to www.something.com?q=%7Bsome%2Bthing%7D.

What do I have to do to get www.something.com?q=%7Bsome+thing%7D?

I'm using jersey-client v1.9.1 and your code run with no error.

Here is my maven dependency:

<!-- https://mvnrepository.com/artifact/com.sun.jersey/jersey-client -->
        <dependency>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-client</artifactId>
            <version>1.9.1</version>
        </dependency>

And the java code:

import java.net.URI;

import javax.ws.rs.core.UriBuilder;

public class Main {
    public static void main(String[] args) throws Exception {
        try {
            URI url = UriBuilder.fromUri("www.something.com")
                    .queryParam("q", "{some thing}")
                    .build();
            System.out.println(url);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

The output: www.something.com?q=%7Bsome+thing%7D

UPDATE

The curly braces are the reason for failing with v1.19 (see the documentation)

Here is a working version for v1.19:

        URI url = UriBuilder.fromPath("www.something.com")
                .queryParam("q", "{value}")
                .build("{some thing}", "value");
        System.out.println(url);

You can try this: You need two library jersey-core-1.19.2 and javax.ws.rs and jersey-client-1.19.2

public class ClassTest {
    public static void main(String[] args) throws UnsupportedEncodingException {
        String queryString =  URLEncoder.encode("{some thing}", "UTF-8");
        System.out.println(queryString);
        URI uri = UriBuilder.fromUri("www.something.com")
                .queryParam("q", queryString)
                .build();
        String url = uri.toString().replace("%2B", "+");
        System.out.println(url);
    }
}
