Summary:  Signature: Impossible to re-use key

Original Submission:  According to the Java API documentation, it's only 
necessary to call Signature.initVerify(...) or Signature.initSign(...) once. So 
the following command sequence is allowed:

Signature.initVerify(...);
Signature.update(...);
Signature.verify(...);
Signature.update(...);  <-- SignatureException is thrown
Signature.verify(...);

Classpath's implementations of verify(...) and sign(...) reset the key, but 
they should keep it for reuse.
