Summary: BailErrorStragery alike for ANTLR grammar parsing Key: CASSANDRA-12598 URL: https://issues.apache.org/jira/browse/CASSANDRA-12598 Project: Cassandra Issue Type: Bug Components: CQL Reporter: Berenguer Blasi Fix For: 3.10 CQL parsing is missing a mechanism similar to http://www.antlr.org/api/Java/org/antlr/v4/runtime/BailErrorStrategy.html This solrves: - 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
