Engineering tools from Dassault Systèmes (SolidWorks, CATIA) and Siemens (NX, Teamcenter) often hardcode JRE checks. A common issue in 2023-2024 involved a specific hook in 8u241's awt.dll that allowed custom OpenGL rendering pipelines. Newer JREs broke that hook. The official vendor workaround was: "Downgrade to JRE 1.8.0_241." Large banks and insurance companies often run COBOL-to-Java
