byte array to string conversion

[Lars Andersen <lars at rimfaxe dot com>]

In the Mysql jdbc driver I discovered a byte[] to string conversion 
utility that does not work with GCJ.

I made a little test program, maybe someone can tell what's going on.

With Sun jdk 1.4.1 on linux it outputs "toAsciiString -> Test String"

With GCJ 3.3 on linux it outputs "toAsciiString -> "

public class TestStringConversion
{
   private static final int BYTE_RANGE = (1 + Byte.MAX_VALUE) - 
Byte.MIN_VALUE;
   private static byte[] allBytes = new byte[BYTE_RANGE];
   private static char[] byteToChars = new char[BYTE_RANGE];

   static {
       for (int i = Byte.MIN_VALUE; i <= Byte.MAX_VALUE; i++) {
           allBytes[i - Byte.MIN_VALUE] = (byte) i;
       }

       String allBytesString = new String(allBytes, 0,
               Byte.MAX_VALUE - Byte.MIN_VALUE);

       int allBytesStringLen = allBytesString.length();

       for (int i = 0;
               (i < (Byte.MAX_VALUE - Byte.MIN_VALUE))
               && (i < allBytesStringLen); i++) {
           byteToChars[i] = allBytesString.charAt(i);
       }
   }
  
   public TestStringConversion()
   {
   }
  
   /**
    * String conversion as found in com.mysql.jdbc.StringUtils
    */
   public static String toAsciiString(byte[] buffer, int startPos, int 
length)
   {
       char[] charArray = new char[length];
       int readpoint = startPos;
       for (int i = 0; i < length; i++)
       {
           charArray[i] = byteToChars[(int) buffer[readpoint] - 
Byte.MIN_VALUE];
           readpoint++;
       }
       return new String(charArray);
   }
  

   public static void main(String[] args)
   {    
      String test_str = "Test String"; 
      byte[] test_buf = test_str.getBytes();
      System.out.println("toAsciiString -> "+toAsciiString(test_buf, 0, 
test_buf.length));
   }
  
}
