Major It is not possible to use instrumentor.instrumentClass call for class which does have overloaded methods.
Instrumentator adds for each method rule with the same name which ends with parsing error.
E.g. I have a class with two methods called "call" like void call() and void call(String param). The call InstrumentedClass instrumentedClass = instrumentor.instrumentClass(MyClass.class) then ends with error like:
