--illegal-access=deny; support was removed

[vbramselaar]

Summary

These warnings are added to the SVG image and maybe also to the PNG:
OpenJDK 16: Option --illegal-access is deprecated and will be removed in a future release.
OpenJDK 17: Ignoring option --illegal-access=deny; support was removed in 17.0

Like this:

Error parsing SVG image ‘(image :type svg :data OpenJDK 64-Bit Server VM warning: Ignoring option --illegal-access=deny; support was removed in 17.0

Because of these warnings my Emacs preview does not work anymore. When removing the option --illegal-access=deny, the preview works again.

Maybe its a good idea to remove this flag from the defaults so everyone on modern JVMs don't hit this?

As a workaround for the masses: m-x customize-group plantuml. Find Plantuml Java Args, expand, remove --illegal-access=deny. Save and set for current session. Profit.

Ah, looks like fix is here: 2fd42ff

... but perhaps not yet on ELPA (last release I see is 1.4.1)
