However, this promise nearly killed my Christmas last year. Ever used the new fancy ScheduledThreadPoolExecutor? Nice class. Easy task handling in a multi-threaded application design (at least if you dont try to extend it, but this is another story). I've developed my application on Windows, we did extensive tests in a Linux environment and when we delivered the application to our customer's location Friday before Christmas it crashed quite instantly. Within the logger! What's that?

Ever asked yourself what you can expect from the values delievered by the JDK's method System.identityHashCode(Object object) ? My original believe (and I suppose I am not alone here) was that the value reflects somehow the memory address of the given object. Not that I tried to access the object in any obscure way, it was just based on the fact that there are not a lot of more things to assign an identity to an object - implying that identity has something to do with uniqueness for the object's lifetime.

The thing was purchased on the auction, but it was too big to fit in the upper store. So a big wardrope had to give way to stuff the reed organ into the chamber with the piano. But if we remove the wardrope, we also can paint the room ... and the room should have a new basement made of cork anyway ...

OK, all done now and she is happy. And she didn't complain today for me sitting the rest of the evening here at the keyboard :)
