If you receive a JVM sync error, and a message indicating the element is too big, then try the following:
Try resyncing. See “Retrieving applications on the BlackBerry device” for information about synchronizing.
Try selecting a single application, and resyncing. See “Retrieving applications on the BlackBerry device” for information about synchronizing.
Try deleting all applications, using the Delete Data option on the trackwheel, and then resyncing. See “Deleting applications and data” for information about clearing the BlackBerry device’s memory.
If the problem persists, try deleting the application and recreating it using a smaller dataset (for example, you could modify the SQL query to limit the results set), or including only required functionality.
