If not, is more probable you can't obtain new connections from the pool than a memory leak .
You must always close all your Connections, Statements and ResultSets .

I'm assuming you want to find all the (strongly) connected components? For that you can use Tarjan's algorithm (a variant of DFS)
What about a breadth first search to find all connected nodes? Once you have the list of connected nodes, you subtract this... .

Your question makes me think that you expect the write method to consume the entire buffer and try asynchronously... .
SocketChannel.write will in non-blocking mode return the number of bytes, which could immediately be sent to the network without blocking .
