Inputstream is not always closed by XMLSignatureInput

Hello,

In the method updateOutputStream of the class XMLSignatureInput, the proxified InputStream is only closed in case of Exception (this code).

IMO, the close call should be in a finally clause or did I miss the reason of only closing in the catch clause ?

I'm able to reproduce the issue of the ticket SANTUARIO-344. I'm trying to sign a file, then deleting the original file.

Regards,

P.
