Ernst, please stop commenting here, if you think the description in bug #37971 is wrong, just add a comment there.

Because of what I pointed out below,
I would vote for closing #37971 and reopening this bug.

Hm,... I do not understand clear java that way.
I read part of the book and I saw that clear java clears not the memory but clears the classes.
This means that classes are to be reloaded.

This seems to me a feature to ensure that if a java class changes while octave is running, this change is taken into account when the class is used again.

Contrary to understanding this is #37971,
clear java fails if there are still objects in use.

according to 'undocumented secrets of MATLAB-java programming',
clear may be used with parameter java,
clearing all java classes.

Fails if still sth is in use:
Warning: Objects of java/lang/Double class exist  not clearing java
