We put tags in our compiled byte code like
private static final mks_id = "$Id:";
Then our vcs (mks obviously) will usert version numbers when we check in. This allows us to see what version a specific .class file is. This is a pretty common practice, sometimes people put copyright notices ect into their compiled code.
We obviously never actually reference this field, so is there a way for me to tell idea to quick complaining about any variable named mks_id ???
