János Cserép updated WICKET-311:
--------------------------------
Oh, I found it:
final void requestDetached()
{
if (pageMapsUsedInRequest != null)
{
synchronized (pageMapsUsedInRequest)
{
Thread t = Thread.currentThread();
Iterator it =
pageMapsUsedInRequest.entrySet().iterator();
while (it.hasNext())
{
Entry entry = (Entry)it.next();
if (entry.getValue() == t)
{
it.remove();
}
}
pageMapsUsedInRequest.notifyAll();
}
}
}
But that block is also synchronized on the same object... hmm... hmm...
