Antlr4 IntelliJIdea pluggin recovery strategy

[Roberto Mencia]

I've found that my grammar recovers as expected inside the plugin but the parser doesn't behave the same when executed in the code.
For the grammar below, the input :XXX produces 2 different trees, one in the plugin (I believe the correct one, or at least better) and a different tree when executed in code.

Also the error messages I get are different:

• IntelliJIdea => line 1:0 extraneous input ':' expecting {'(', Term}
• Running the code => line 1:0 no viable alternative at input ':'

Is there any setting I can add to my code so that it recovers like the plugin?

Check the images below to see the differences.
Note: The number of X is just a typing error, but it doesn't really change the result

This is a simplified grammar that shows the issue:

grammar Combined1;
compileUnit :    field EOF    ;
field:       
    fieldName ':' value   
    |   value;
fieldName:   Term;
value: 
    '(' value ')'   
    |    Term;

Term:    TERM_START_CHAR TERM_CHAR*;
fragment TERM_START_CHAR:   ~( ' ' | '\t' | '\n' | '\r' | ':' );
fragment TERM_CHAR : (TERM_START_CHAR | '.' );
WS  :    [ \t\r\n\f]+ -> skip;
