Hi Art,

Thats sounds like word for word the practices that we follow. Although I did just double check the code to make sure and I found a couple of places which had manual lock/unlock's in them which should not have.

From Session.java

public void awake()
	{
		ecLockManager().lock();
		super.awake();
		.....


public void sleep()
{
// Need to check as this gets called after terminate() when logging out
synchronized (ecLockManager)
{
if (ecLockManager().isLocked())
{
ecLockManager().unlock();
}
}
super.sleep();
}

I wrap anything other than super.... in try...catch(Throwable), just in case.

Now this may be a basic Java question and I tried to ask it yesterday, but probably in a very poor fashion.


When your dealing with overriding a method and the original method does not throw an exception, but you do in your over-ride you receive a compile error something like....

"terminate() in Session cannot override terminate() in Session; overridden method does not throw java.lang.Exception"

Which means that any exceptions that are thrown you need to deal with them at this methods level, correct ? Or is there a way to throw them without this message appearing
