Can Java based server with 100k thread survive

Question

I want to host a application from home. My local machine: Core i7 2600 4 core,8 thread and 16GB memory Fiber: 100Mbps

My Target: 100k workerthread, each thread have its own while loop.

Will my machine survive. Code Sample:

serversocket obj_sock=new serversocket()
while(true){
new thread(new workerthread(obj_socket.accept());
}

class workerthread implements runnable{
      public workerthread(socket sock){
           rs=sock.getinputstream()
           ws=sock.getoutputstream()
       }
      public void(run){
        while(true){
         //do read stream, write stream
        }
      }
}

PS I skipped exceptions in code.

The default thread stack size on my 64-bit Java 8 is 1M. That means that 100,000 threads will need 100G of RAM to work with. That is tunable, and you could probably get under 16G, but software would require more testing with a constrained stack.

It seems like operating systems will let you create that many threads.

I would strongly suggest looking into an event-driven (ie non-blocking) protocol framework like Netty or Apache MINA to implement your server.
