I am confused about all these versions. How come if you download the

this explains it. The platform manager expects a JDK, not a JRE. The
concept of JRE is a bit dated and no longer well defined since the
introduction of jlink, which allows to create your own JRE if needed.
I thought we added a better error msg in case a user tries to register a
JRE - apparently not ;)
you get Java 8 since the JDK went all the way up to 21?
yeah. so here is the summary:
- NetBeans 21 requires JDK 11, 17, or 21 to run as you can see on the
download page.
- You should be able to register JDK 8 or later using the java
platform manager and use it for your projects.
- 1.7 won't be possible anymore since the editor of NB relies on a
recent version of javac (which is bundled with NB), and javac itself
does no longer support the Java 7 target (8 works fine)
How come if you download the latest...
The Platform Manager itself can download JDKs.
This community maintained website might also help to find a version from
a vendor you prefer: https://javaalmanac.io/
If you install a JDK using tools like sdkman or a regular repository on
linux, NB should automatically add it to the platform manager since it
scans some well-known directories.

NetBeans 21 supports projects which use JDKs in the rage 8-21 with
limited support for early access dev builds 22, 23 etc.
javac itself dropped support for the 1.7 target in Java 20.
So your best bet would be to try NetBeans 17 which used nb-javac
based on JDK 19. Although I can't promise that this will work since I
don't think anyone tested anything with Java 7 for quite some time.

I have just installed Nebeans 22 which is using JDK 21.
I need to maintain a desktop application which is on JDK 1.7 but
when I attempt to add this JDK and even JDK 1.8, Netbeans gives the
following error ...
"Cannot detect and install the selected platform. The Java or javac
may not be executable."
I have read in other forums that this was a bug way back in version
10 or 11.
I would have imagined that this would have been solved by version 22.
Does anyone know some fix or workaround for this?
