Does the BlackBerry Java SDK support 1.5 syntax? If not, has there been any hints that this is something that could be coming?

              Can you use retroweaver to make a 1.4 version of your Java 5 code?

              I have a strong suspicion that the SDK is limited to 1.3, does retroweaver require 1.4?

                According to http://retroweaver.sourceforge.net/ it targets 1.4.  I don't believe there was a byte code format change between 1.3 and 1.4, so it might still be usable with careful usage (so you stay within the 1.3 capabilities).  Worth a try?

              Blackberry is based on Java ME which is JRE 1.3. I would love Sun/Oracle to bring Java ME up to JRE 1.5 but I know of no effort to do that at present.

              I believe I've seen that Java ME is to be replaced by Java SE, but I cannot locate it right now.  http://java.sun.com/javame/index.jsp does not immediately indicate this to be the case.

                @Thorbjorn: We can only hope.  JME is the bane of my (professional) life.
