1. The KVM was originally part of the Spotless system, a Sun research project. See http://www.sun. com/research/spotless/.
2. A MIDP application could conceivably launch a denial-of-service attack (that is, sucking up all the processor's time or bringing the device OS to a standstill). It's widely acknowledged that there's not much defense against denial-of-service attacks. Applications and applets in J2SE suffer from the same vulnerability.
3. A better idea would be to redesign your application so that complicated stream processing isn't necessary on the device. In general, you should make your server do as much work as possible and your MIDlet do as little as possible.
4. Color depth is the number of bits that determine the color of a pixel on the screen. One bit allows for two colors (usually black and white). Four bits allows for 16 colors, which could be different levels of gray or a palette of other colors. In general, N bits allow 2 to the power of N colors or levels of gray.
5. MIDP implementations are not required to recognize all varieties of PNG files. The documentation for the Image class has the specifics.
6. You are probably familiar with the try - catch blocks that are used in Java for exception handling. The finally clause is not as well known, but it is very useful. Code in the finally block will be executed regardless of how control leaves the try block.
