[NETBEANS-5080] Detach the request of DebugSession to avoid infinite …

…loop(to finish the task)

https://issues.apache.org/jira/browse/NETBEANS-5080

DebugSession may be started via other ways.
e.g. via command line: `nc -vz localhost 9003`
In such a case, the debugger does not receive anything.
An infinite loop occurs because it waits until it receives data.
So need to detach the request when the debugger stops.
