Looks like a bug; it works in ksh.That is, in fact, what is happening. I'm not sure you can call it a bug, though -- bash is behaving exactly as documented.
Where exactly is that documented? The only statement I can find in the documentation referring to this problem is:
"When braces are used, the matching ending brace is the first `}' not escaped by a backslash or within a quoted string, and not within an embedded arithmetic expansion, command substitution, or parameter expansion."
I may be wrong, but to me this means that the first opening brace matches the last closing one, and that the token ${HOSTNAME/.*} is a correct parameter expansion.
