"Some input files use unchecked or unsafe operations."

416044Sep 8 2004 — edited Nov 22 2008
When i compile my (1.4.2_05) Java project I get the following
       [javac] Note: Some input files use unchecked or unsafe operations.
       [javac] Note: Recompile with -Xlint:unchecked for details.
Is there any doc explaning this? At http://java.sun.com/j2se/1.5.0/docs/relnotes/features.html#javac I found a note about this "-Xlint" option, but I want to know what code is producing this "unchekced/unsafe" operations.
