But i'm wondering why there isn't a global jvm system option for the
new Thread(runnable).start() to perserve stack traces at least until
the start method.
Seems like a no brainer so that tools (like the netbeans debugger) can
find where the misbehaving threads originate from, (instead of like
now, where i have to depend on the names). Or am i missing something
obvious?
You don't need the VM for that, something like that should work:
public class ThreadEx extends Thread {
final Throwable where;
{
where = new Throwable();
setUncaughtExceptionHandler(new UncaughtExceptionHandler() {
@Override
public void uncaughtException(Thread t, Throwable e) {
setLastCause(e, where);
e.printStackTrace();
}
});
}
static void setLastCause(Throwable t, Throwable where) {
for(;;) {
Throwable cause = t.getCause();
if (cause == null)
break;
t = cause;
}
t.initCause(where);
}
}
