Still seeing errors in STDErr after removing ErrorListeners

[syepes]

Hello,

I am building a configuration file parser and I need to remove all the error output messages, so I have tried removing the error listeners:

parser.setErrorHandler(new BailErrorStrategy())
parser.removeErrorListeners()

But when I run the parser I am still getting errors in the standard error output:

line 1:0 token recognition error at: ' '
line 1:1 token recognition error at: '■'
line 1:0 token recognition error at: ' '
line 1:1 token recognition error at: '■'
line 1:0 token recognition error at: ';'
line 1:0 token recognition error at: ';'
line 1:0 token recognition error at: ' '
line 1:1 token recognition error at: '■'
line 1:0 token recognition error at: ' '
line 1:1 token recognition error at: '■'

Is this normal?
whats the best method for removing these errors?

Best regards,
Sebastian

I believe you also need to remove the error listeners from the lexer separately from the parser.
