The following fix
" Add -Dsun.perflog.fx.firstpaintexit and move properties to PrismSettings
  Reviewed by: Richard B — snorthov / detail"
broke performance logger. No logging is printed anymore as PerformanceTracker.isLoggingEnabled
is equal to false now.

To reproduce the issue run any application with flags:
 -Dsun.perflog.fx.firstpaintflush=true -XX:+PerfDataSaveToFile -Dsun.perflog=file://C:/temp/results.log


C:/temp/results.log is not generated any more.
The issue was introduced in promoted build 8.0-b107, everything works fine with 8.0-b106
