Ups, I simply forgot to write it to the OutputStream. My fault.
I checked it twice now and I don't know why, but the NonSeq parser log
the exception that the stream can not be decrypted, but don't fail to finish
parsing. The legacy parser fails hard and stop parsing the rest of the document.
All I want to say is, that the NonSeq parser run into the same error but handle
it better. Failing the whole decryption because one object can't be handled
isn't good.
There are also cases where the NonSeq parser isn't working, So not every user
can just switch to it. Maybe you remember the "signature" discussion ;-) This
is one TODO I try to fix, but at the moment I haven't time to do it.

The case with the exception is, that the NonSeq parser already ignore it
silently and just log it. So both parser would act the same, if the new
exception block will be also logged and ignored. All I want to say is, that the
NonSeq parser run into the same error but handle it better. Failing the whole
decryption because one object can't be handled isn't good.

I read a lot about the BadPaddingException and learned the the usage of the
CipherInputStream should be avoided. I've replaced at least one piece of code
to avoid the particular stream and now the BadPaddingException is gone. There
is still one part left which doesn't seem to be critical but maybe it's a good
idea to change that part as well
