What surprises me is that Octave apparently just adds "/jvm.dll" to
JAVA_HOME rather than including the hierarchy below JAVA_HOME up to server/
I noted this on my Mageia Linux system as well.

FYI, there are some clues here:
https://savannah.gnu.org/bugs/?func=detailitem&item_id=40111

One of the comments there (#31) mentions that JAVA_HOME may only have
forward slashes for Octave being able to use it - can you try if that works
better?
If so, and if your other programs won't work anymore then, could you file a
bug report about JAVA_HOME needing to accept backward slashes on Windows.

Philip
