  • I'm not sure what I am really reloading the class. How can I check it?

    Well, you could print a message to System.out in static initializer in your class. If the message is printed you will know that your class has been reloaded, and the (new) class has been initialized.

    See Pretty printing a method in ASM Bytecode

    Whether netbeans special instruments for it?

    I don't know what you are asking here ...
