Java Web Start window title problem

I've written a JavaFX application that uses Java Web Start. For some reason, the window title 开发者_StackOverflow中文版is always "Java" (on Linux) or blank (on Windows). However, the desktop icon has the correct application title and image.

From what I've found so far, the important bit here is the information > title element in the JNLP file.

What am I missing?

NOTE: I'm happy to post my JNLP content if someone says it would be of use.

It turns out that the application title and icon for the taskbar entry are controlled by the title and icons attributes of the Stage.

Only the title and icon of the desktop icon are controlled by the JNLP.
