RFR: 8317834: java/lang/Thread/IsAlive.java timed out [v2]

[Darragh Clarke]

> Currently the `IsAlive` test occasionally times out.
> 
> This PR changes the timeout from `10` to `25` which I think is an adequate increase based on the failures I've seen. Though I'd be happy to change it to another value if someone thinks `25` isn't ideal.
