29*b1cdbd2cSJim Jagielski  * We need a generic interface to forward any oneway uno interface method
30*b1cdbd2cSJim Jagielski  * by using threads to the original object. Reason:
31*b1cdbd2cSJim Jagielski  * It's not allowed to call synchronoues back to the office if a java object
32*b1cdbd2cSJim Jagielski  * was called in a oneway declared interface method. Then it must be
33*b1cdbd2cSJim Jagielski  * executed asynchronoues. To do so - a thread can be created which use this
34*b1cdbd2cSJim Jagielski  * interface. It get the object, which whis to be called back and the type and
35*b1cdbd2cSJim Jagielski  * parameter of the original request.
