Processing following JNLP file causes initialization of HTTPS handler that does load browser certificates
on startup (from static initializer).
However, there are no https connections created and certificates are not used.

N/A

Initialization of https handler happens because JNLP file mentions https URL in the homepage tag.

One obvious thing to fix is that we should delay loading certificates until first connection is created.

However, we probably should not instantiate https handler at all as homepage attribute is not really needed to start webstart application. Perhaps parsing XML descriptor we can be more lazy.

Test results for tentative fix show ~2% improvement on minimal FX applications. 
Note that app_jws_swing and app_swing had not show any significant change and this is fine as they do not use FX extensions.

  * - Not Significant: A non-zero %Diff for the mean could be noise. If the
      %Diff is 0, an actual difference may still exist. In either case, more
      samples would be needed to detect an actual difference in sample means.
