The most interesting question to me isn't what it throws, but what
it can catch.
If I can write this in a Java CNI implementation function, then I'm
happy:
void myJavaClass::NativeMethod(int parameter)
{
try {
nativeCPPLibrary::globalFunction();
} catch (nativeCPPLibrary::myException x) {
throw new myJavaException(x.failCode);
}
}
In the 3.0 version I was playing with, this code was illegal. In fact,
referring to both C++ exceptions and Java exceptions in the same object
file failed.
