  Modified:    docs/manual/CoreTasks javac.html
  Log:
  The manual strongly encourages you to specify source/target levels, yet it 
gave no examples that did so! Putting
  in some usages to plant the bug in people's minds. (Especially important for 
people just starting to use JDK
  1.5, which changed the default source level.)
