I finally got around to applying this. Please see the
HANDLE_WIN32_EXCEPTIONS in JNIException.h. I used a CPP class from
http://www.codeproject.com/cpp/exception.asp and it seems to work well
(I wrote a few testcases). Although I am not that fluent in writing CPP
macros/defines so if either of you thinks that there is a smarter way to
 do this, please feel free to change it.

And since I was in the process of updating the license information with
the relevant info for this class, I also added license information for
Apache Xalan and Xerces used by the Type Browser.
