Fix test failure

#137

Hi @leochr ,
I just opened the PR as I thought this was relatively simple, and I thought I could make a contribution here.
I corrected the reference to the resource file, but even after that, a test case was failing, and I found it was a timeout when switching the service(/health) between UP and DOWN. So, I increased the Thread.sleep() value from 600, and I started to get consistent results at 1500.
To check if it is something related to my local setup, I checked out a previous commit (6ec559) and found 600 was working fine there. So I doubt some recent changes may have affected the app's performance (perhaps I'm wrong). Is it something to be concerned about?

@Amalraj-Joseph-IBM Thanks for taking a look at the issue and the PR. The changes look good to me.

As for the timeout, I am not sure. @fmhwong the Health-related tests work fine with mpMetrics-5.0 and mpConfig-3.0 but consistently fail with mpMetrics-5.1 and mpConfig-3.1 [when Thread.sleep(600) is used]. Is this a known performance degradation?

We haven't updated mpHealth for a while. No sure if the server was slow to update the configuration. @pgunapal Can you take a look?
