The 'public void java.util.Properties.save(OutputStream,String)' signature has been changed
to 'public void java.util.Properties.save(OutputStream,String) throws IOException' in jdk1.2beta3.

The following example no longer compile on jdk1.2:
----- Here is the test (Props.java) -----
public class Props {
 
public static void main(String argv[]) {
  System.getProperties().save(System.out, "System Properties");
}

}
---- Here is the compiler output (JDK-1.1.5) -------
% javac Props.java
%
---- Here is the compiler output (JDK-1.2beta3-G) -------
% javac Props.java
 
Props.java:4: Exception java.io.IOException must be caught, or it must be declared in the throws clause of this method.
  System.getProperties().save(System.out, "System Properties");
                             ^
1 error

%
-----------------
The source changed to match this change
  try {
    System.getProperties().save(System.out, "System Properties");
  }
  catch (java.io.IOException e) {
  }

will not compile on jdk1.1.x (giving the following error message "Exception java.io.IOException is
never thrown in the body of the corresponding try statement")
