I see the following error in my log

I only see this logged as error during startup, I did not even use M2E.

I still this at a client also in the error log with M2E - Maven Integration for Eclipse 2.4.100.20230827-1557 org.eclipse.m2e.feature.feature.group Eclipse.org - m2e

It does not seem to make a functional impact but the exception is re-created twice during restart.

I got this error too when doing upgrade tests on the Eclipse IDE for RCP and RAP developers from 2023-09 to 2023-12 M1. On some simple experiments I cannot see this error when running 2022-12 M1 or 2023-09 on its own, it was only after upgrading that the problem happens. Doing a second try with the upgrade showed the same error.

Running Eclipse with -clean resolves the error.

Thanks for the tip @jonahgraham. I now see The -clean (osgi.clean) option was not successful. Unable to clean the storage area: C:\dev\Eclipse\eclipse-2023-12-M1\eclipse\configuration\org.eclipse.osgi but the error described here is gone. ;-)

happend to me too.

Happens for me with each test run (Sloeber) and clean does not fix it.
