Unable to parse new array expression with LR rule

[sharwell]

With the current algorithm, it is not possible to parse certain expressions with an LR rule. One basic example is the new array expression in Java:

Grammar:

grammar T;
s @after {System.out.println($ctx.toStringTree(this));} : e EOF ;
expressionList
    : e (',' e)*
    ;
e   : INT
    | 'new' type ('[' e ']')+
    | e '[' e ']'
    ;
type: ID
    | ID '[' ']'
    ;
ID : ('a'..'z'|'A'..'Z'|'_'|'$')+;
INT : '0'..'9'+ ;
WS : (' '|'\\n') -> skip ;

Failed expression:

new T[1]

Expected:

(s (e new (type T) [ (e 1) ]) <EOF>)
