Research direction
Start by reproducing the failure through the Eclipse save participant 'Code Clean Up' and the explicit formatter shortcut, using the reported Eclipse, Java 21, and Linux environment. Compare both behaviors with the working external java -jar invocation. Done means the Eclipse plugin formats successfully without the MarkdownPositions initialization error while standalone formatting remains working.

Description
Issue:
- Just bumped to
1.36.0, I have a save action to format automatically, getting this error:- A save participant caused problems. The save participant 'Code Clean Up' caused an exception:
java.lang.NoClassDefFoundError: Could not initialize class com.google.googlejavaformat.java.javadoc.MarkdownPositions. See the error log for details.
- A save participant caused problems. The save participant 'Code Clean Up' caused an exception:
- Explicit invocation of the formatter (Shift + Ctrl + F) does nothing.
- External runs via java -jar are fine.
