As stated in the commit +message of <https://gerrit.libreoffice.org/#/c/69730/> "javavendors_*.xml <updated> should not have +been updated...": "Changing <updated> causes jfw_startVM and jfw_getSelectedJRE (both +jvmfwk/source/framework.cxx) to fail with JFW_E_INVALID_SETTINGS, which in turn causes functionality +that requires a JVM to issue a GUI error dialog stating that the user must select a new JRE in the +Options dialog. While that behavior makes sense if a JRE was selected that would no longer be +supported by the modified javavendors_*.xml, it is just annoying if an already selected JRE is still +supported. And a compatible change to javavendors_*.xml implies that an already selected JRE will +still be supported." |
