>                 Key: CASSANDRA-12598
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12598
>             Project: Cassandra
>          Issue Type: Bug
>          Components: CQL
>            Reporter: Berenguer Blasi
>            Assignee: Berenguer Blasi
>             Fix For: 3.x
>
>
> CQL parsing is missing a mechanism similar to 
> http://www.antlr.org/api/Java/org/antlr/v4/runtime/BailErrorStrategy.html
> This solves:
> - Stopping parsing instead of continuing when we've got already an error 
> which is wasteful.
> - Any skipped java code tied to 'recovered' missing tokens might later cause 
> java exceptions (think non-init variables, non incremented integers (div by 
> zero), etc.) which will bubble up directly and will hide properly formatted 
> error messages to the user with no indication on what went wrong at all. Just 
> a cryptic NPE i.e
