I observe several problems with UI shown from deploy code:
   1) If i launch app with Java console enabled it pops and shows text ok.
       However, thumb is shown expanded to all witdth as in case when all content is visible.
       But once you touch it trying to move it resizes quickly and shows way more content.

   2) All popups have some empty transparent border on the right and bottom side.
       May be it is drop shade or something similar. And may be it is because i am running in Virtual box where prism is not available.
       But it look weird.

   3) More information dialog is shown once i click on details button and supposed to show exception.
       It comes out too small and exception can not be read.
       It also look weird if resized - content resize horizontally only. Vertical resize does not work correctly and leave transparent holes.

See screenshot for details (odd windows background rectangle is sideffect of making virtual box screenshots on Mac :)).
