/* Bug 4753245
* WBN 11/22/02
* The in.close() method was missing -- causing problems when trying to delete this file in
* other code -- at least until the garbage collector gets around to closing it.
* Normally I wouldn't put this inside a try/catch -- an error ought to be returned,
* but this is a special low-risk-toleration time. Adding the try/catch is safer. The
* code will behave exactly like before if an Exception is thrown. It can't possibly hurt anything
* to add the close()
