The function parseInt has a missing size check. This leads to a StringIndexOutOfBoundsException with the following reproducer:

parseInt("");

Java/Maths/ParseInteger.java

Lines 18 to 22 in a60cb58

    
           public static int parseInt(String s) { 
        
               if (s == null) { 
        
                   throw new NumberFormatException("null"); 
        
               } 
        
               boolean isNegative = s.charAt(0) == '-';
