java.lang.OutOfMemoryError

[Tang, Charlie Y.]

Hi   I have a problem of OutofMemoryError when updating my screen continuously every second after about a day or so               Below is the thread that does all the updating /**              * This thread will take care of updating the Dom structure              * and the object              */                     public class RunUpdate extends Thread             {                         int delay;                         private boolean threadSuspended;                         RunnableUpdate ru = new RunnableUpdate();                                     RunUpdate(int d)                         {                                     delay = d;                                     threadSuspended = false;                         }                                                 public synchronized void pausethread()                         {                                     if(!threadSuspended){                                                 threadSuspended = true;                                                 notify();                                     }                                                             }                         public synchronized void resumethread()                         {                                     if(threadSuspended){                                                 threadSuspended = false;                                                 notify();                                     }                         }                                                                         public void run(){                                                                                                         while (true) {                         try {                                                          if (threadSuspended) {                                 synchronized(this) {                                     while (threadSuspended)                                         wait();                                 }                             }                            //Need by Batik inorder to refresh the svg canvas                                     Thread.sleep (delay);                                     um = svgc.getUpdateManager();                                     System.gc();                                                                                                     um.getUpdateRunnableQueue().invokeAndWait(ru);                                                                                     } catch (InterruptedException e){                                     System.out.println("RunUpdate over");                         }catch (java.lang.OutOfMemoryError err ){ //in case of memory error                                     System.exit(1);                                                                          }                                          }                         }                                                 public class RunnableUpdate implements Runnable                         {                                     public void run(){                                                             update();            //method to update the dom structure                                          }                                     }             }                                       I’m guessing the problem is the RunnableUpdate ru added to the RunnableQueue causes a RunnableQueue.Link object to be created to link to every Runnable Update And that does not get deleted eventhough there is only one instances of RunnableUpdate and that’s ru. ? is there a way to update my screen continuously and indefinately? Thanks a lot   Charlie Tang
