killing an infinite loop in java

Question

I am using a third-party library to process a large number of data sets. The process very occasionally goes into an infinite loop (or is blocked - don\'t know why and can\'t

Answer 1

Put the call to the library in another thread and kill this thread after a timeout. That way you could also proces multiple objects at the same time if they are not dependant to each other.

EDIT: Democode request

This is pseudo code so you have to improve and extend it. Also error checking weather a call was succesful or not will be of help.

for (Object data : dataList) {
    Thread t = new LibThread(data);
    // store the thread somewhere with an id
    // tid and starting time tstart 
    // threads
    t.start();
    }

while(!all threads finished)
{
    for (Thread t : threads)
    {
        // get start time of thread
        // and check the timeout
        if (runtime > timeout)
        {
            t.stop();
        }
    }
}

class LibThread extends Thread {
    Object data;

    public TextThread(Object data) 
    {
        this.data = data;
    }

    public void processData() 
    {
        Object result = TheirLibrary.processData(data);
        store(result);
    }
}
