* ENT-6357: Deserialize LedgerTransaction elements for each Contract.verify(). * Lock the LedgerTransaction and NetworkParameters objects down for contract verification. * Refactor BasicVerifier to be package private instead of public. * Simplify verifyConstraints() operation. * Review fixes: replace HashSet with LinkedHashSet, and add signing parties to commands via mapIndexed. * Ensure tests also run notary nodes "out of process". * Streamline SerializationContext switching. * Cache deserialised cryptographic instances during contract verification. * Invoke Class.forName() instead of ClassLoader.loadClass() to reduce contention on the system classloader's lock. * Deserialization cache key now pre-computes its hash code. * Allow AttachmentsClassLoader to be used concurrently. * Cache all Envelope objects for reuse during contract verification. * Generate CertPathProxy hash code using conventional algorithm. * Adjust CustomSerializer.Proxy to allow better access to SerializationContext.
