I have added some more things to Dave Griffith's Inspection Gadgets. This version has been tested with IDEA #2013 and is only compatible with Pallada. You can download it here:
empty (static) initializers are now detected by "Statement with empty body"
Constant naming convention no longer flags "serialVersionUID" as an error.
unnecessary FQN's that use same package as that to which the Java file belongs are now flagged as an error by "Unnecessary fully qualified name"
New quick fixes for:
Assignment used as condition
Class explicitly extends java.lang.Object
See here for the change list of the previous version:
Thanks for Inspection Gadgets Dave!
