Research direction

Start by inspecting the thumbnails4j-all dependency graph and the build metadata that brings in ooxml-schemas-1.4.jar and poi-ooxml-schemas-4.1.2.jar. Confirm how the duplicate AlternateContentDocument class enters the artifact, then verify that the published artifact no longer contains duplicate classes or the classloading ambiguity.

Written by the indexing model from the issue text.

Description

bug

the thumbnails4j-all artifact has two transitive dependencies:

  • ooxml-schemas-1.4.jar
  • poi-ooxml-schemas-4.1.2.jar

which contain duplicate classes. One example is: com.microsoft.schemas.compatibility.AlternateContentDocument$AlternateContent$Choice$Factory

This could lead to unexpected behavior at runtime, and would be dependent on classloading order.
