java.blogs apparently gets confused when I updated the title of a blog entry - the updated blog becomes the newest entry and my subsequent blog entry does not appear on the java.blogs front page, nor on the blog details page.
I apologize to java.bloggers for being lead to my old entry yet again.
I may yet have to re-add by blog unless this fixes itself soon. (It's an unresolved issue.)
EDIT: It appears that an update of my blog details fixed the problem.
