The title element is an optional element (since jnlp spec version 8.20, the whole information element is optional.
If you have no title element, and either have a shortcut hint element, or have jcp set to always create shortcuts or to always ask, then the follow behavior will be seen:
1.) The user will be prompted (or all-permission dialog will state that shortcut will be created).
2.) The shortcut will not be created.

We either need to handle the no title situation by creating a canonical title, or not prompt user or show info line in all-permission more info dialog, and document that title is required to create shortcut.
