RUNJVA RESTART(*YES) or ENDJVA to restart the Java Virtual Machine

One of the reasons that I till now only have seen java used in batch jobs is, that you have absolutely no control over the Java Virtual Machine (JVM) once it is started. Environment variables are for example only initialized once. This means you can't use it for interactive jobs because you don't know what has been done before that. The JVM could have been started by another process delivered by another company with other settings.
So we need a way to end / restart the JVM in a job.


Use Case:

In an interactive job it should be possible to specify something like RUNJVA RESTART(*YES) or ENDJVM or ENDJVA.
Then you have control over the environment.
The same should be possible if you are referring to Java objects in RPG.

    It's a limitation on i. We can not invoke JVM twice within one job. In fact, like ???JAVA" or ???RUNJVA" CL command, they would not affect current interactive job. Instead, they would create a new job to invoke the ???java" in it. After that, the secondary job would end, and current interactive job could continue invoke the JAVA or RUNJVA commands.
