JSR-282 SI 23.0
------------------------------------------------

Summary
---------------------
Add getCurrentSO() to Scheduler.

Specification References
---------------------
This will add two new static methods to the Scheduler base class.

Problem being Addressed
---------------------
There is no general way to get a reference to the currently-executing schedulable object.  getCurrentRealtimeThread() works if the SO is a RTT, but if it's and AEH, there is no easy way.

Proposed Solution Summary
---------------------
Add the following two methods to Scheduler:

static public boolean isCallerAnSo();
static public Schedulable getCurrentSO();

Semantics
---------------------

static public boolean isCallerAnSo();

If the caller is an SO (a real-time thread or an AEH), return true.
IF the caller is a Java thread, return false.

Static public Schedulable getCurrentSO()

Return a reference to the caller's SO.  If the caller is not an SO, throw ClassCastException.


Discussion Points
---------------------
Should we drop isCallerAnSO()?  It can be determined without the method and without throwing an exception, e.g., 
if (Thread.currentThread instanceof RealtimeThread){
  Schedulable currentSO = Scheduler.getCurrentSO();
} else {
  //	we're not an SO, do something else.
}


Compatibility Issues
---------------------
No "non-standard" issues.
