> The following test has been seen to fail as below in some runs where the machine is
under heavy load and slow running options are specified and the isValid() call takes more
than a second to return.

> assuming it will return in one second. For embedded the int parameter is not implemented
so indeed this always passes. For the Network implementation in NetConnection40.java we actually
do timeout and perform a query as part of the implementation so might indeed return false.
