Security risk or Something to be concerned about?

Hi all. I noticed in my connection log that after I did an update for a Java Program, about 5 minutes later I had the following entry in my connection log. I did not make an out bound request as far as I know:

 

9:08am  Inbound connection   127.0.0.1   local service port 50750  from 127.0.0.1 remote service port 50751

0 bytes sent  40 bytes received     

 

9:08am Outbound connection   127.0.0.1   local service port 50751  from 127.0.0.1 remote service port 50750

40 bytes sent  0 bytes received 

  

9:09am Inbound connection   127.0.0.1   local service port 50752  from 127.0.0.1 remote service port 50753

0 bytes sent  40 bytes received     

 

9:09am Outbound connection   127.0.0.1   local service port 50753  from 127.0.0.1 remote service port 50752

0 bytes sent  0 bytes received  

 

1. I am most concerned about the unsolicited inbound request

2. Is this normal?

3. Does this show some type of security risk or intrusion?

Again most concerned about the unsolicited inbound

I use Norton Antivirus 2008 and a Vista Home Premium OS with the Vista Service Pack 1
