How antlr turns off runtime error logging
This is the output from the default error reporter - it is telling you that your input is syntactically incorrect. You can clear the error handlers on the parser object and it will stop telling you that, but your input will still be incorrect (or your grammar is incorrect).
Most people install their own error handler to gather errors in a way that makes more sense for their application. Look at the source code for the default error handler for clues.

Use either parser.removeErrorListeners() or lexer.removeErrorListener(ConsoleErrorListener.INSTANCE);
