Neil, thank you for sharing your experience with this matter.
Concerning NB's tool-menu „Java Platforms“ and its three tabs, tab 1
"Classes" and tab 2 "Sources“ und tab 3 "Javadoc“, let's take a closer look
at tab 2 and tab 3, because after some additional testing I found the
solution for the problem – which btw already exists with former OpenJDK and
NB versions at least on Ubuntu/Debian Linux:
(a) NB compiles its editor's keyword Javadoc Ctrl+SPACE support only from the
(Java) src.zip specified in tab 2.
(b) Only NB's editor right-click menu "Show Javadoc" uses the folder/URL
specified in tab 3 to open an external browser with this Javadoc's html file.
In Ubuntu 20.04 LTS I had the optional package "openjdk-17-doc" installed, so
(b) worked fine, but the optional package "openjdk-17-source" wasn't
installed, so (a) didn't work. The problem was solved by installing the
latter package, (clearing NB's cache) and re-start NB so that it re-scans its
default "Java platform" and automatically fills all 3 tabs correctly.
So now we Ubuntu/Debian Linux users just need to ensure that actually all of
the following three apt-packages are installed, in order to use NB 12.5 's
Ctrl+SPACE Javadoc support also with OpenJDK 17 (and previous OpenJDK versions) :
(1) openjdk-17-jdk
(2) openjdk-17-doc
(3) openjdk-17-source
Hopefully this helps other Ubuntu/Debian users, too?
Greetings,
Hans

Did you install the openjdk-17-doc package? Might help here.
For further testing, in the Java-Platform's Tab "Javadoc" I manually added
the URL for the online
Javadoc:https://docs.oracle.com/en/java/javase/17/docs/
Possibly tryhttps://docs.oracle.com/en/java/javase/17/docs/api/ which
is what I've got in 12.6-rc3.
