“ArrayIndexOutOfBoundsException”The input array size is larger than the array limit

[Cici-Musse-Lee]

The file path is org.zkoss.json.parser.Yylex.
In our test case, pass int1=2147483647 into the function whose api is yycharat().
Inside this api, an array with a size greater than 2147483647 will be created, and an array out-of-bounds exception will be generated at this time.

source code：

public final char yycharat (int pos){
        return zzBuffer[zzStartRead[pos];
}

test code:

public void test_yycharat_1_36() throws NoSuchFieldException,IllegalAccessException{
        int int1=2147483647；
        java.io.Reader reader2 = null;

        org.zkoss.json.parser.Yylex yylex0 = new org.zkoss.json.parser.Yylex(reader2)；
        yylex0.yycharat(int1);
}

test result：

java.lang.ArraylndexOutOfBoundsException:Index 2147483647 out of bounds for length 16384
