I'm getting the following error running the latest version of Eclipse (2023-03) on M1 arm64 MacBook:

I reinstalled Eclipse 2023-03 and just the Open Liberty Tools from the zip here in #460 and Validation Error went away. However, the pom.xml and two .sh files now display with an odd red dot. There are no problems reported though, and I can manually validate these files (which generated the error above before).

@wnm3 I believe this red dot issue has been fixed in 2023-09 (see https://github.com/OpenLiberty/open-liberty-tools/issues/485) . Can you check please?

Closing this as I believe this is fixed in WDT 23.2. Please reopen if you have issues
