JVM-TERMINATE Method (factory method)
Explanation
The current thread is isolated from the Java VM. In the multithread applications, the
current thread must be isolated from Java VM before the thread is terminated.
Also, when it is called by the last thread in a process, Java VM is terminated. It is
used when the adapter class is used no more.
Syntax
INVOKE FJ-JAVA-CONTROL "JVM-TERMINATE"
Caution

current thread must be isolated from Java VM before the thread is terminated.
Syntax
