One way to answer- “which one”  Brew, IBM, Nokia, Android?   Well lets look at the real deal- Sun Java.  How will this work for embedded devices:

DEFINITIONS…. The use of Software in systems and solutions that provide dedicated functionality … or designed for use in embedded or function-specific software applications, for example but not limited to: Software embedded in or bundled with industrial control systems, wireless mobile telephones, wireless handheld devices, netbooks, kiosks, TV/STB, Blu-ray Disc devices, telematics and network control switching equipment, printers and storage management systems, and other related systems are excluded from this definition and not licensed under this Agreement.

Now, the interesting thing is the license between Sun and the people with Java clones.  Does that pass on this exclusion?
