this is a simpler grammar,but it seems it does what you want:

grammar Xx;
start: report EOF;
report: (comment { System.out.println("comment: " + $comment.text);} 
           | text { System.out.println("text: " + $text.text);} )+; 

comment: COMMENT;
text: TEXTCHR+;

fragment NEWLINE: ('\n' | '\r');
COMMENT: '-*' (~NEWLINE)* NEWLINE;
TEXTCHR: (  ~('-') 
	|  ('-') ~'*') => '-'
         );
