[antlr-interest] Parser Generation: How to catch an exception within an rule?

[luciano mantuaneli]

Greetings!
I have a rule called identifierStar, which throws an MyOwnCheckedException exception.
I have another rule called importDefinition, which invokes relu x. My question is how can I catch the MyOwnCheckedException exception?

importDefinition
    options {defaultErrorHandler = true;}
    { boolean isStatic = false; String imp = "";}
    :    i:"import"^ {#i.setType(IMPORT);} ( "static"! {#i.setType(STATIC_IMPORT);} )? imp=identifierStar SEMI!
    ;


identifierStar returns[String result = ""] throws StarImportException{
    StringBuilder sb = new StringBuilder("");
}
    :    i:IDENT{sb.append(i.getText());}
        ( DOT^ i2:IDENT {sb.append("." + i2.getText());})*
        ( DOT^ STAR {throw new StarImportException();})?
        {
            result = sb.toString();
        }
    ;

Thank you very much!
