[antlr-interest] Stack Overflow in the tree parser

[Fan Yang]

Hi All,
 
When I'm using java parser(generate in C#) to parser the following code, StackOverflow Exception was threw in the tree parser. the problem is deep recursive function call in array initializor. 
 
 Would you please tell me how to deal with this problem(not mean to increase the stack size). Any suggestion will be appriciated.

    public Object[][] getContents() {
        return new Object[][] {
            { "LocaleString", "ja" }, // locale id based on iso codes
