[Code] Method parameter redundancy

[pavly-gerges]

The method TaskExecutorsManager#executeMethod(Worker, Method, MethodArguments, TaskExecutorsManager) has a redundant parameter TaskExecutorsManager, this should be removed and replaced by this.

[pavly-gerges]

This method is an insidious utility inside the object TaskExecutorManager and should be corrected as it violates the object-oriented programming (object methods should perform on "this" object).
