This is not a very good pattern for a number of reasons.

First, you cannot control logging at the source of the error. Admittedly this is an error message but I have run into times where I want to turn off the klaxon to see what the real problem is.
Second, constructors should not have side effects. It's never a good idea.
Third, I never log an error if I am throwing an exception. It just adds noise. I will, however, log additional useful information that is not in the exception message. Just parroting what's in the exception is of little value.
Finally, what the heck is ERR_04007? :) I thought there already was a discussion and community consensus about how there is little to negative value in using numbers as error messages. Maybe I missed the conversation where this opinion was reversed. If so, ignore this bit. :)
+1 - we need to find a way to make this easier to read either with the IDE's help or other.
Pardon I realized this was discussed further and that I had not read this completely. Retracting the +1. Too much mail.
