Trying to get Class with parameter that is generic

I am trying to instatiate a class from a String using:

Class configClass = Class.forName(configClassName);
Class testClass = Class.forName(className);
Constructor constr = testClass.getConstructor(configClass);
TestCase testCase = (TestCase) constr.newInstance(configClass);

The constructor in the class RecursiveLinkTest that extends TestCase looks like this: 

public RecursiveLinkTest(Class<JsonConfig> configClass)

As you can see the parameter in RecursiveLinkTest is of the typ Class. How can i get the constructor for the class? I am getting NoSuchMethodException when I run my code. (It can create the Class objects configClass and testClass).

I think this will solve your problem:

Constructor constr = testClass.getConstructor(Class.class);

You need to get the constructor with the Class as the argument.
