RE #2: JVM issues?
RE #1:
The way I typically do this is a case like this:
class StartableDemo implements Startable, Runnable
{
private static boolean m_continue = true;
public void start() {
new Thread(this).start();
}
public void run() {
while (m_continue)
{
// do important stuff
}
}
public void stop() {
m_continue = false;
}
}
In this case, MRUStore will start this up like:
initialize()
{
this.janitor = new StartableDemo();
this.janitor.start();
}
dispose()
{
this.janitor.stop();
this.janitor = null; // remove reference so it can be garbage collected
}
