Our parser logic relies on methods being available on specific classes / interfaces from mongodb-java-driver. In the linked ticket, we even noticed that a small change in the API surface led to disruption in our parsing logic.

To avoid this situation in production, we should run nightly tests against the nightly builds of mongodb-java-driver, at-least the codeinsight tests. This should surface any parser related problems if the driver API surface changes and affects the parser.
