"1.6.0 refers to exactly the same platform and products numbered 6".
"The number 6 is used to reflect the evolving level of maturity, stability, scalability and security of Java SE." (Is that some sort of superstitious Chinese numerology? I thought the devil is 6.)
"JDK" is not an abbrieviation for "Java Development Kit", but "Java SE Development Kit". (Where did the 'S' go?)
"Java EE Development Kit" is abbrieviated "SDK". (Aha, there's the 'S'.)
"Java SE keeps the version number 1.6.0 (or 1.6) in some places that are visible only to developers, or where the version number is parsed by programs." (Oh, except for the filenames and install directory of every Java download non-developers might use.)
Whoever decided and approved this crazy scheme is obviously a Microsoft sleeper agent devoted to the destruction of the Java platform. Sun, kick them upstairs quick, before they do any more damage.
