Initial bytes incorrect after Java AES/CBC decryption
...on Vector (IV).
It's been a long time since I last read about AES, IVs and block chaining, but your line
IvParameterSpec ivParameterSpec = new IvParameterSpec(aesKey.getEncoded());
does not seem to be OK. In the case of AES, you can think of the initialization vector as the "initial state" of a ...
Efficiency of premature return in a function
...t the goto example below, to use a break-less switch/case inside the catch block above. One could switch(typeof(e)) and then fall through the free_resourcex() calls but this is not trivial and needs design consideration. And remember that a switch/case without breaks is exactly like the goto with da...

difference between throw and throw new Exception()
...s the stack trace, destroying all stack trace information until your catch block.
NEVER write throw ex;
throw new Exception(ex.Message); is even worse. It creates a brand new Exception instance, losing the original stack trace of the exception, as well as its type. (eg, IOException).

What is the difference between SAX and DOM?
..."DOM parsers".) That would be very handy for the user (I think that's what PHP's XML parser does), but it suffers from scalability problems and becomes very expensive for large documents.
