FULL PRODUCT VERSION :
C:\temp
est>java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
Take the following trivial class that prints out its arguments:

public class A {
        public static void main(String[] args) {
                System.err.println("args >");
                for(int i = 0; i < args.length; i++) {
                        System.err.println(args[i]);
                }
                System.err.println("args <");
        }
}

Run the following command on Windows under 32 bit Java 6:

C:\temp>java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) Client VM (build 20.45-b01, mixed mode, sharing)

C:\temp>java A -d64
args >
-d64
args <

The -d64 parameters is passed correctly to the Java program.

Under Java 7, 32 bit:

C:\temp
est>java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing)

C:\temp
est>java A -d64
Error: This Java instance does not support a 64-bit JVM.
Please install the desired version.

My application expects to receive the -d64 argument, but udner Java 7 it is not being delivered

Note:

a) It occurs with 'java -jar A.java -d64' also
b) the java usage message is:

C:\temp
est>java
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)

Which states that anything after the classname (or after '... -jar jarname') should be passed as an argument




REGRESSION.  Last worked in version 6u45
