kasia in a nutshell: The abuse and over-use of toString()
The scary part is how many experienced programmers have no clue about this little gotcha.. go spread the word.
Yikes. And there's the following related anti-idiom :
public void foo(Object whatever)
{
if(whatever.equals(THE_CONSTANT))
...
}
Every time I see this, it breaks my heart.

use StringUtils from jakarta commons lang it checks for null and keeps your code clean
