I tried to reproduce the issue using version 1.0.0-RC1, following the code and Maven dependencies you provided, but I was unable to replicate the problem. Could you provide a minimal demo project that can reproduce the issue? Additionally, Spring AI 1.0.0 GA has already been released — you could also try that version to see if the issue still persists.

setIgnoreContentStreamSpaceGlyphs was added in pdfbox 3.0.4 which is the version expected by Tika, however, the spring-ai-pdf-document-reader is using 3.0.3. We need to keep these in sync.

I'm using Spring AI 1.0.0. Is there a way to work around this problem without moving to snapshot version?

[dafriz]

Yes you can add pdfbox version 3.0.4 as a dependency to your project and exclude the dependency from ai-pdf-document-reader.
