What do you look for in Code reviews?

We do a lot of this unconsciously during code reviews, but when asked we turn a blank face.

• First the usual suspects, is the code doing what is functionally required, business logic, especially if the team member is new
• See that there are no hard-codes, standards are being followed.
• Is there chance to make something configurable, like lookups. See that these are being read from properties files or the database, that way any new additions don't need a code release.
• Are connections, jndi lookups being cached.
• Code re-use, both classes and methods.
• Kludge.
• Performance considerations, StringBuffer vs String and so on.
