Thank you for your reply. I am sure you are correct, as I am using
Jaunch with java-21.
Here is the output of the updater for the *.toml files.
and for fiji-linux
Can you tell me the correct way to fix this (ie, shoudl I remove local
files and have the updater replace them)?
Best regards

Hi Aryeh,
Sorry to hear about the trouble with the Morphology plugins. It sounds
like a classpath problem, probably because of the nested file
structure, and not something wrong with the plugin jar itself.
My first guess is that your installation was converted to the Jaunch
launcher (e.g. fiji-windows-x64.exe) at some point and you have an old
copy of $FIJI_HOME/config/jaunch/fiji.toml. Around lines 104/106 there
should be something along the lines of "
'!—plugins|${app-dir}/plugins/*/*.jar'," and if that's missing then
you'll definitely see a ClasNotFoundException when running Morphology
commands.
If I'm correct and you are using Jaunch, I would run Help > Update...
> Advanced and make sure your fiji-xxx launcher and
config/jaunch/*.toml files are up-to-date with the Java-8 update site.
I verified that the Morphology plugins are working for me on Windows
with both the Jaunch and original ImageJ-xxx launchers, on Java 8 and 21.
Let me know if that's not the case or these files are up-to-date for
you and you're still seeing the error.
Best,
- Mark

I did not think to try that.
Yes -- it works properly with a freshly downloaded ImageJ (that is not
FIJI).
