[7u6] Review request for 7159381: [macosx] Dock Icon defaults to Generic Java Application Category

[Leonid Romanov]

Hi,
Please review a fix for 7159381: [macosx] Dock Icon defaults to Generic Java Application Category. The problem here is that we ignore the fact that for the bundled app its icon might be specified via Info.plist file. In this case OS X sets the icon for us, so we don't have to do anything.
