4.3.2

This update improves the behaviour of run methods on sessions and transactions in synchronous and asynchronous APIs. Specifically, the Result object is returned only when there is a successful response for the dispatched request, otherwise an exception is thrown. In Bolt terms, it waits for the RUN message response. This also means the Result keys are always available and the keys method just returns them and does not rely on network communication. The example below illustrates the basic difference:

// before
Result result = session.run( "not-cypher" );
result.keys(); // <- blocking call that throws an exception

// after
Result result = session.run( "not-cypher" ); // <- blocking call that throws an exception

The reactive API will be updated in subsequent releases.
