LG KG320 User Manual page 214

The software may be blocked or switch itself on when
Java applications not specifically developed for the phone
this manual refers to are downloaded, making it necessary
to "restart" the handset. We would like to point out that
these problems are caused by incompatible applications
and are not a product fault.
! Caution
Only J2ME (Java 2 Micro Edition) based programs
will run in a phone environment. The J2SE (Java 2
Standard Edition) based programs will only run in a PC
environment.
