Hi all,
I've just discovered that while
Double test = true?null:0d; //result: test is null
works without error, the following
Double test2 = true?(new Object(){public Double testMethod(){return
null;}}.testMethod()):0d; //<-Throws NPE
Throws a NullPointerException. :-/ Ok, that sucks, so what about this?
Double test3 = new Object(){public Double testMethod2(){return
null;}}.testMethod2(); // result: test3 is null
Double test4 = true?test3:0d; //<-Throws NPE
Also throws a NullPointerException. I suspect this has something to
do with the autoboxing, because
Object test5 = true?new Object(){public Object testMethod3(){return
null;}}.testMethod3():0d;
Works fine. I'm running OS X 10.5 and java 1.5 here at work. Is this
a known issue? Or is this somehow expected behavior?
Ramsey
