1/23 I'm trying to make somebody else's code thread-safe and it seems like
my synchronization blocks are not being respected. Does anyone know
a problem with this code?
class FooPoller {
protected static Boolean lock = new Boolean(true);
private static void poll() {
// do some stuff
synchronized(lock) {
// modify some static member objects
}
}
Public void addToList(Vector addable) {
// do some stuff
synchronized(lock) {
// modift some static member objects
}
}
}
I then have one thread calling FooPoller.poll() in a loop, while some
other thread is calling addToList() on an instance of a subclass of
FooPoller. Do the instance method and the static method see a
different lock? Do the base class and the subclass see a different
lock? This is really stumping me. -dgies
\ What Java version? Perhaps something weird is happening
with Boolean autoboxing if >=1.5. Try an Object instance
as the lock. - gojomo
