Notification triggers to many listeners after startup

[moroff]

With my program, a total of six sensors are connected with two GPIO pins each (e.g. pin 15 and 16). At the sensor output (and thus at the GPIO input), one pin is high and the other low.
If a sensor is triggered for the first time, events are generated for other pins on which no level change has taken place. I guess for all input pins whose level is high.

With the next signal change everything works fine.

I guess the problem might be in the class PgioSocket#notificationReceived, the element lastGpioLevelMask is changed only in this method, but does not respect the initial values correctly.
