NumberKey returns wrong number

[Matt Finn <ma...@bitcount.com>]

Hi, 

I've been having problems with the NumberKey(long) constructor.

The following statement outputs "9900000000000000":
  
  System.out.println((new NumberKey(9900000000000001L)).toString());

This is because NumberKey(long) uses the BigDecimal(double)
constructor and introduces floating point errors:

The constructor should use the valueOf(long) static factory method 
to avoid the conversion errors.

     public NumberKey(long key)
     {
-        this.key = new BigDecimal(key);
+        this.key = BigDecimal.valueOf(key);
     }

Regards, 

Matt
