Examples of org.apache.commons.io.FileCleaningTracker.exitWhenFinished()

org.apache.commons.io.FileCleaningTracker.exitWhenFinished()
Call this method to cause the file cleaner thread to terminate when there are no more objects being tracked for deletion.
In a simple environment, you don't need this method as the file cleaner thread will simply exit when the JVM exits. In a more complex environment, with multiple class loaders (such as an application server), you should be aware that the file cleaner thread will continue running even if the class loader it was started from terminates. This can consitute a memory leak.
For example, suppose that you have developed a web application, which contains the commons-io jar file in your WEB-INF/lib directory. In other words, the FileCleaner class is loaded through the class loader of your web application. If the web application is terminated, but the servlet container is still running, then the file cleaner thread will still exist, posing a memory leak.
This method allows the thread to be terminated. Simply call this method in the resource cleanup code, such as {@link javax.servlet.ServletContextListener#contextDestroyed(javax.servlet.ServletContextEvent)}. Once called, no new objects can be tracked by the file cleaner.
