Execution result of byte code generated on Win32 is incorrect.
Could not handle a value "4.94065645841246544e-324" properly.

import java.text.*;

public class minval{
    public static void main(String[] args){
        double d1 = Double.MIN_VALUE;
        double d2 = 4.94065645841246544e-324;
        if(d1 != d2){
            System.out.println("NG");
            System.out.println(d1+" "+Double.doubleToLongBits(d1));
            System.out.println(d2+" "+Double.doubleToLongBits(d2));
        }else
            System.out.println("OK");
    }
}

If above code is compiled on Solaris then gets exptected result.
But if Win32 then gets unexpected result.

sishida@stones[293] java minval <--bytecode compiled on Solaris
OK
sishida@stones[294] java minval <--on Win32
NG
4.9E-324 1
1.0E-323 2

From a redundant report (4031719), another test case:

The following delightful java program:

public class Bug {
    public static void main (String[] args) {
String doubleMinVal =

    double minVal = Double.valueOf(doubleMinVal).doubleValue();

    System.out.println("Double: " + minVal);
    System.out.println("Long bits: " + Double.doubleToLongBits(minVal));
    }
}

produces this (correct) output on Solaris:

Double: 4.9E-324
Long bits: 1

and this (bogus) output on win32:

Double: 1.0E-323
Long bits: 2
