| | | // shadowing anything that is already bound to INADDR_ANY/PORT. |
| | | // While technically correct, with IPv4 and IPv6 being separate |
| | | // address spaces, it presents a problem to end users because a |
| | | // common case scenario is to have a single service serving both |
| | | // address spaces ie listening to the same port in both spaces |
| | | // on wildcard addresses 0 and ::. ServerSocket implemantation |
| | | // does not provide any means of working with each address space |
| | | // separately such as doing TCP4 or TCP6 only binds thus we have |
| | | // to do a dummy connect to INADDR_ANY/PORT to check if it is |
