JSQLParser skip UDF token evaluation

Question

Consider the following code

        String sql ="SELECT NAME, ADDRESS, COL1 FROM USER WHERE SSN IN ('11111111111111', '22222222222222') and abcd_exists(fn,v -> isNotNull(v));";
        Select select = (Select) CCJSqlParserUtil.parse(sql);

Now, since the function abcd_exists is not recognized, the parse would throw an exception.

Is there a way to bypass the validation in JSQLParser? I would want to "tell" not validate abcd_exists(fn,v -> isNotNull(v)) part of the sql statement.
