IPC Socket
IPC Socket is a Java wrapper around interprocess communication (IPC) using java.net.ServerSocket and java.net.Socket as the API.
On Unix-like systems, it uses Unix Domain Socket. The path is a filesystem path name.
On Windows, IPC is implemented using Named Pipe. The path must refer to an entry in \\?\pipe\ or \\.\pipe\.
See unit tests for the details.

Why not just use TCP/IP?
TCP/IP is open to everyone on the network, if someone can get hold of your machine, the person could connect to it. This raises security concerns for some usages (like build tools) since it could lead to arbitrary code execution if used without authentication.
