J2ME Security Integrity

• Memory Management
• Garbage collection simplifies application
  development and eliminates memory leaks
• The Java VM can decide if an object resides in
  flash or RAM. This is transparent to the
  applications
• Security
• Java applications cannot escape their sandbox
• Byte-code verification ensures applications are
  well formed and cannot compromise system
  integrity
• Sensitive APIs and data can be protected from
  rogue applications
