I don't think that would be necessary, at least for Java. It seems like 
a reasonable restriction (for us) not to try and throw through OS 
frames.

So, is the problem:

a) there is/was a bug in the unwinder that causes it to try and throw 
into OS frames even though you have an enclosing try block, or
b) common C++ code on windows expects to be able to throw through the 
OS ?
