[Octave-bug-tracker] [bug #39073] java_get wrong return type

[Ernst Reissner]

Follow-up Comment #2, bug #39073 (project octave):


Yes ist is obviously a problem with auto(un)boxing. 
How it should work to be ML-compatible is described in

I have the impression, that the problem returning a double although i have an
object other than of class java.lang.Object 
occurs in case the according class has a method doubleValue(), like
java.lang.Number. 
In fact the problem not being able to display the proper class 
seems to have to do that i extend java.lang.Number. 
Or maybe that i implement ernst.reissner.Number, i.e. my own number, which has
the same short name as the one from java.lang. 

I think something is implemented relying on a half truth. 
But maybe not so difficult to fix.
