How do I ignore stuck threads in a Weblogic Server

Question

I've got the below code working on Weblogic Application Server 10.3.2. The long running task executed on timerExpired takes longer than the server wide StuckThreadMaxTime of 600 seconds. I do not want to modify this value, but just to ignore the stuck thread timeout for this particular thread of processing.

I can see how this can be accomplished using a commonj WorkManager from this: http://download.oracle.com/docs/cd/E11035_01/wls100/config_wls/self_tuned.html#wp1069945

And then by adding the following to the work-manager tag in the weblogic.xml file:

<ignore-stuck-threads>true</ignore-stuck-threads>

But how on earth do I do the same for a Timer/TimerManager?

web.xml

<resource-ref>
 <res-ref-name>tm/TestTimer</res-ref-name>
 <res-type>commonj.timers.TimerManager</res-type>
 <res-auth>Container</res-auth>
 <res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>  

TestTimer.java:

import commonj.timers.Timer;
import commonj.timers.TimerListener;
import commonj.timers.TimerManager;

public class TestTimer implements TimerListener {
    public void init() 
       TimerManager timerManager =    
          (TimerManager)initContext.lookup("java:comp/env/tm/TestTimer");
       timerManager.schedule(this, SCHEDULE_DELAY);                             

    }

    @Override
    public void timerExpired(Timer timer) {
        // perform long-running task    
    }
}

I took the easy way out (time pressures) by doing the processing in work scheduled by a WorkManager when the timer expires.

public MyClass implements TimerListener, Work
    @Override
    public void timerExpired(Timer timer) throws Exception {    
        WorkManager workManager = initContext.lookup("wm/myworkmanager");
        workManager.schedule(this);                 
    }

    @Override
    public void run() {
        doWork();
    }
}

web.xml

<resource-ref>
    <res-ref-name>wm/myworkmanager</res-ref-name>
    <res-type>commonj.work.WorkManager</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>

weblogic.xml

<wls:work-manager>
    <wls:name>wm/myworkmanager</wls:name>        
    <wls:ignore-stuck-threads>true</wls:ignore-stuck-threads>
</wls:work-manager>
