While loop wont break unless there is a print statement in it

I am using a while loop to wait for actions in a jpanel to finish (occurs on button press in another class) but the while loop never breaks it self

For example this will never break even when bool_enabled is set to false

Code:

---

while (jpnl_mainMenu.bool_enabled)
            {
              //even after adding this check it doesn't break, it is like the loop is not executing
              if (!jpnl_mainMenu.bool_enabled)
              {
                  break;
              }
            }

---

This however, will break when bool_enabled is set to false

Code:

---

while (jpnl_mainMenu.bool_enabled)
            {
              System.out.println(bool_enabled);
            }

Why does the loop only break if there is a print statement?

You need a label to break out of nested blocks:

Code:

---

        outerLabel:
        while (jpnl_mainMenu.bool_enabled)
        {
              if (!jpnl_mainMenu.bool_enabled)
              {
                  break outerLabel;
              }
        }

---

I don't think that's the problem as something like this wont get to the print statement (even though bool_enabled is false) and then would never reach the break but the code below the while is not executed so it hasn't broken out of the loop.

Code:

---

while (jpnl_mainMenu.bool_enabled)
            {
                    if (!jpnl_mainMenu.bool_enabled)
                    {
                        System.out.println("g");
                    break;
                    }
            }

How is bool_enabled getting set to false?
There's nothing in that sample that shows it being false.
