Re: Timer already canceled

Joel,


Another thing you might check is your heap size (if you are using a 
geronimo version below 2.0).  Since I started working with 2.0, I have 
been able to set a rather low minimum heap.  When I was working with 1.x 
versions (and Java 1.4) I needed to increase my heap size or I would get 
'timer already cancelled' errors.  There was a JIRA created for this to 
make the error message reflect what had actually happened but I don't 
know if it got fixed (just checked it and it's still open).

Try setting a higher maximum heap size for Java and try again - maybe 
that will be all you need.

Jay,
Excellent point. Something about this problem was bothering me, but I  
just couldn't remember what... Time to do something about this class  
of error, I guess. Although it's hard to make it foolproof.

Even with the Jira (https://issues.apache.org/jira/browse/ 
GERONIMO-2114), I had a hard time remembering how this error could  
occur...

So, let me try again...

java.util.Timer creates a Thread which is used to dispatch Task  
execution. If an Error or RuntimeException occurs on this Thread, the  
Timer will be marked as "cancelled". Any further attempts to use this  
Timer will result in a Timer already cancelled IllegalStateException.

We can do the following:

1) catch Throwable in TimerTask.run() and log errors. Note that  
errors could still occur in the Timer Thread which we cannot catch...
2) catch IllegalStateExceptions thrown by Timer.schedule() and throw  
an exception explaining that an OOME might have caused the error.
