RFR 8048840: File.createTempFile has uninformative failure message

[Bernd]

Hello,

Do you think this fixes the complaints? I can imagine that "" or "~" is
used, and including this in the exception does not really help. "Prefix
string too short, must be 3 characters" would be my choice, but I wonder if
the restriction is very usefull anyway?
