[eclipse-dev] Fatal error opening webapp projects after upgrading to ecl

[Jean Pierre URKENS <jean-pierre.urkens@xxxxxxxxxxxx>]

I upgraded eclipse from 2024-09 to 2025-03 and now it fails to open my web application projects reporting ‘error Loading descriptor for <projectname>’ with following stack:

Any idea what is causing this?
