timeline of release as free software
The article is unclear and lacks sources about the timeline of Sun publishing JDK under the GNU GPL. They announced on May 8th that they have released the source code. Was anything released prior to May 8th? Does the May 8th release cover everything? Any help would be good. Thanks. Gronky 23:36, 9 May 2007 (UTC)
- The exact dates are probablly burried on suns site somewhere but iirc what happened was we got a couple of little bits (the compiler and vm) first. Then we got the main code drop and there has been slow development on that since. There is not yet a release that is both fully functional and free of encumberments.

java component == loader == interpreter == JVM? == HotSpot?
This article states the following about JDK's java component
- java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler.
Is this java component the actual Java Virtual Machine (which imho for the JDK is HotSpot)? --Abdull (talk) 19:35, 3 October 2010 (UTC)
JDK vs. SDK
So, I've found pages from oracle.com that strongly suggest that they use the term JDK to refer to extra features accompanying the basic SDK needed to interpret Java source code into class files. The Java SE 7 JDK download page says that the JDK contains "tools for developing, debugging, and monitoring Java applications". The current download page for Java EE 7 offers Java EE with the SDK or with the SDK and JDK, which, by the way, makes abundantly clear that they do not use these terms interchangably. Note, however, that both bundles come with documentation, and so the inclusion of documentation is not what differentiates them, according to Oracle. The installation instructions for Java EE 7 SDK make clear that the "JDK 7" is required to use it. Interestingly, the link for "JDK 7" takes you to the Java SE JDK download page, which is specifically what they are referring to when they speak of the "JDK". There does not appear to be any kind of separate Java EE JDK or Java ME JDK.
Their readme on JDK 7 lists components in the JDK, but it is not clear at first glance which of these would be in a, say, Java EE SDK. Both obviously come with the JRE, but I'm not finding any reliable sources that straight-up compare the two.
And so, what we can say with certainty, according to what Oracle says and not according to so many web sites that quote this article:
- JDK and SDK are considered two separate things
- Java EE SDK can be downloaded with or without the JDK
- The JDK they refer to is specifically the one for Java SE
- There is no software package that Oracle calls "Java EE JDK" or "Java ME JDK". There is only the Java SE JDK.
So I'll have the article reflect this information. If anyone finds verification of another understanding of this, please share it here. Again, reliable sources are needed. Quoting from websites and forums that quote from older versions of this very Wikipedia article won't cut it. Ender and Peter 16:30, 10 July 2013 (UTC)
