If a ServerSocketChannel has been registered for SelectionKey.OP_ACCEPT
at a Selector, select() will return immediatly with OP_ACCEPT on that
Channel, even when there is no connection waiting.
See example attached.
Compile and run it with:
gcj-3.3 --main=Server Server.java && ./a.out
and it will output:
Before selector
Something was selected.
Before accept.
and hang in the ServerSocket.accept() method until a connection
happens.
Using gcj-3.4 (20040314):
Before selector [waiting]
Something was selected.
Before accept.
