JDK-6959569 - need automated testcase for custom progress bar
Description
Current custom progress for JavaFX starts showing progress from 60-70% and then slowly moves till 100%. 
This is likely to happen because FX runtime consist of several files of different sizes and small files are loaded fast.
Progress is also shown with delay and therefore first part of download is not visualized. 

We need to improve perceived impression.
Comments
EVALUATION Consider: - providing sizes with jar entries in the JNLP and allocating progress chuncks proportionally - "rescaling the overall progress" - whatever is current state when progress is shown have to be zero
