Crash when I try to make a Wikidata query

CVE-2020-36518

Need to update the package: version > 2.13.2.2

I tried to run SparqlClient to query Wikidata (code very similar as in the main README file).
Build tool: Maven

<dependency>
  <groupId>com.bordercloud</groupId>
  <artifactId>SPARQL-JAVA</artifactId>
  <version>1.0.9</version>
</dependency>

Exception is thrown in Runtime:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.http.client.utils.URIBuilder.setCharset(Ljava/nio/charset/Charset;)Lorg/apache/http/client/utils/URIBuilder;

As far as I can tell, this library will currently send the default Apache HttpComponents User-Agent header to the query service (though I haven’t tested it). It should allow users to customize this (and ideally use a default that identifies this particular library).

Errors to fix.
Replace == by equals for String.

How can i get a list of entities with russian encoding?

TODO: ask the token before sending the SPARQL query:

• https://www.oauth.com/oauth2-servers/access-tokens/client-credentials/
• https://www.oauth.com/oauth2-servers/access-tokens/password-grant/

The token will be revoked when the class is deleted by the garbage collector.

If the token is obsolete, request it again.
