javax.crypto.SealedObject.getObject(Cipher c) does not work

Name: ktR10099 Date: 10/17/2003



Attempt to retrieve original object from the SealedObject using
getObject(Cipher) method fails. Please find below example, demonstrating
the problem. It worth mentioning, that getObject(Key) method works OK.
