That was exactly the problem. That's what we get for trying to use the latest! Thanks for the quick response, Steve!

The cause is due to changes made in scala-xml 2.2.0, which based on the backtrace looks like is what you are using. We have a pull request to upgrade scala-xml to 2.2.0 in Daffodil and fix this, but it is still waiting on another review: https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Fgithub.com%2Fapache%2Fdaffodil%2Fpull%2F1060&data=05%7C01%7Clara.blatchford%40nteligen.com%7Cf30b2c44436c4ce32e6008db934a3f9c%7C379c214c5c944e86a6062d047675f02a%7C0%7C0%7C638265719343645744%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=HPEkmYqX5vDj7I1NLMrAKNAjN0R3pvlh6Mj%2FCKMjqro%3D&reserved=0 However, that should not affect Daffodil 3.5.0 since it still depends on scala-xml 2.1.0, which does not have this problem as far as I know. Have you manually upgraded to 2.2.0 yourself? I think downgrading scala-xml should fix this for you. - Steve On 2023-08-01 05:16 PM, Lara Blatchford wrote: > Hello - In attempting to upgrade from Daffodil 3.3.0 to 3.5.0 I'm > running into the issue that compilation of any DFDL schema causes the > exception below.
