Run some tests conditionally of Java being present Some (non release) architectures do not have Java support in Octave, so this patch prevents an FTBFS on those. We could additionally add a Build-Depends on default-jre-headless on those architectures were Java support is there, but keeping the architecture list in sync with the main octave package is error-prone, so we avoid it.
Require version 3 of xmlbeans for POI+OOXML interface As of 2023-03-01, Debian unstable includes the combination of apache-poi version 4 and xmlbeans version 4. This breaks the POI+OOXML interface (see #1012016). . By requiring version 3 of xmlbeans, we ensure that the broken combination will not happen, because it is hard for a user to understand what is going wrong. . In practice this means that POI+OOXML will be disabled (and the OCT interface will be the only available one for reading .xlsx files), unless the user manually installs xmlbeans 3. . As a consequence, the xlsx-poi autopkgtest has been disabled.
