These implementations also tended to be far less optimized than Sun’s. As such these terms did not satisfy the requirements of either the Open Source Initiative or the Free Software Foundation to be considered open source or free software, and Sun Java was therefore a proprietary platform. Major additions included an extensive retooling of the AWT event model, inner classes added to the language, JavaBeans and JDBC. In a paper called Further, he proposed to Sun that its engineers should produce an object-oriented environment based on C++.

Programming languages are typically outside of the scope of the phrase “platform”, although the Java programming language was listed as a core part of the Java platform before Java 7. The language and runtime were therefore commonly considered a single unit.
