PlantUMLMacro fails to load with Python 3.10

[Hendrik Fuß]

After installing PlantUMLMacro as egg under /var/www/trac/plugins, the plugin does not show up on the plugins page.

In trac.log I found an error message:

           ^^^^^^^^^^^^^
SyntaxError: multiple exception types must be parenthesized (macro.py, line 115)

Using Python version:

$ python3 --version
Python 3.10.12

I'm using trac 1.5.3, which is the latest version available from my package repository. I will try upgrading to 1.6, but I guess macro.py is likely to fail on both.

A duplicate of #14337. This plugin is not compatible with Python 3 yet.

Fixed in [18647]. Please try the latest and feel free to reopen it or create an new ticket if you encounter an issue.
