• please support -target 1.4
  As I understand it, Generics "happens" at compile-time and the resulting byte code is no different than 1.4. Generics ultimately just winds up placing the cast operation in the byte-code for you.

  If this is true, I should be able to compile my Generics code and specify a -1.4 target.

  Consider this a plea from someone who has a large existing userbase using Java 1.4 who may not upgrade to 1.5 for many years. I want to play with Generics now :-)

  I second this, I'd like to use Gernerics in J2ME apps. :)

• hmmm....
  So now we have to work with method signatures like this:

  public static > T max(Collection coll)

  instead of method signatures like this:

  public static Object max(Collection coll)

  ... are we sure we want this?!?
