No, it isn't. But it soon will be. See whether this Java website link helps.

I guess that you really meant to ask "Are Sun's JRE and JDK open source?". The answer to that question is as Campbell already said: almost, but it's not completely open source yet. Almost all code of Sun's JRE and JDK has been open source, but Sun used some third-party code in their JRE and JDK that they cannot make open source, because they don't have the rights for it. Currently there are a number of people working to replace that code with open source code, so that it will be completely open source.

Note that there is already a 100% open source Java, called GNU Classpath. But it's only a partial implementation of Java 1.4 and it runs very slow compared to Sun's Java.

I do not know what people mean by open source, but all Java sources are freely available. Everybody can also contribute in development of next version of JDK.

That's right, in the OpenJDK project.
