htmlunit-client 1.1.5 is not compatible with htmlunit 2.57.0 and Jquery 3.7.0 #615

Hi we have a project build on richfaces 4.0.0. Iam trying to upgrade Jquery from 1.5.1 to 3.7.0. After upgrading Jquery, I upgraded htmlunit and htmlunit-core-js to 2.67.0 from 2.17 . But still my tests are failing with error
java.lang.NoSuchMethodError: com.gargoylesoftware.htmlunit.WebRequest.getCharset()Ljava/lang/String;

at org.jboss.test.faces.htmlunit.HtmlUnitEnvironment.getPage(HtmlUnitEnvironment.java:90)

Which means the htmlunit-client which iam using is not compatible with htmlunit and html-core-js.

org.jboss.test-jsf htmlunit-client 1.1.5 net.sourceforge.htmlunit htmlunit 2.67.0 net.sourceforge.htmlunit htmlunit-core-js 2.67.0

Could you please let me know how to solve this?
