Details:
The function usejava is meant to return whether a specific java feature is
available. But in the specific case of 'usejava ("jvm")' the Matlab
documentation says:
> Java Virtual Machine software (JVM) is running.
This is quite different. In the case of Octave, initialization of the JVM is
delayed until required so I usejava should return false until that happens.
And usejava should not initialise the JVM either.
Alternatively, we can say that Matlab documentation should not be interpreted
literally in this case. We can say that in Matlab, having the JVM running is
the same as having the JVM available because it's initialization happens
either at startup or never and that "fixing" this would actually make things
more complicated.
Anyway, here's a bug for discussion on whatever gets decided, for future
reference.
