The START JAVA statement starts the Java VM. The main use is to load the Java VM at a convenient time so that when the user
starts to use Java functionality there is no initial pause while the Java VM is loaded.
The database server must be set up to locate a Java VM. Since you can specify different Java VMs for each database, the java_location
option can be used to indicate the location (path) of the Java VM. See java_location option.
