Criticisms
While the framework is general, Sun currently provides support only on Java ME. For some subjects, such as media locators, it is in effect superseded by other locator standards on platforms such as BD-J.
A point of confusion is that in platforms supported as of 2008, examples such as the SvcDispXlet example from the introduction to the API, written circa 2001, are not deployable because it uses AWT widgets such as java.awt.Button. Most iTV platforms, along with BD-J, implement Personal Basis Profile with no AWT widgets, as opposed to Personal Profile which includes the widgets.
Sun's reference implementation for Java TV attempts to limit its exposure to support issues to the full Java Media Framework by having its own small version of JMF that is internally referred to as "jmflite". As with the limitations of the MIDP emulators that Sun provides, the Java TV reference implementation provided by Sun has not been updated to make provisions for later JDK's such as removing calls to Thread.stop. The Thread.stop method was made a "final" method in Java 1.5 (meaning that classes which extend Thread and override stop will fail at runtime under JRE 1.5 when the class is loaded). This implies that Sun has not yet committed to public plans or a roadmap for taking Java ME beyond JRE 1.3. If such an upgrade were to take place, it would require significant work on the part of all vendors of Java ME-enabled devices.

Famous quotes containing the word criticisms:
“I have no concern with any economic criticisms of the communist system; I cannot enquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the system is based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments ... but we have in no way altered the differences in power and influence which are misused by aggressiveness.”
—Sigmund Freud (1856–1939)
“The sway of alcohol over mankind is unquestionably due to its power to stimulate the mystical faculties of human nature, usually crushed to earth by the cold facts and dry criticisms of the sober hour. Sobriety diminishes, discriminates, and says no; drunkenness expands, unites, and says yes.”
—William James (1842–1910)
