I think that some of the iText classes are messing with the provider like
creating/removing sessions. But i can not figure out if this is true.
I though it might be Provider problem and i wrote to them, but they ensure me
the problem is not at the provider .dll file.
If I get the private Key and use it to sign many files i got this exception:
java.security.ProviderException: Could not obtain session

The exception is thrown at line : "Signature.initSign(PrivateKey);"And this
happens at file 100 all the time. Does someone know why?
If I create new Provider every 90 files i get the first exception i posted.
The strange is that i get the exception at different file every time, but after
file 100.
Seems like some classes are playing with the provider sessions!!!
