Could not open Base files since update.
After updating my iMac to BigSur, LibreOffice to 7.0.3.1 and JDK to 15.0.1 I still have a message stating that "No Java installation could be found" when attempting to open an exiting .odb. Is this a new issue or a known issue?
Using "still" makes me assume the error existed already before any updates...
To answer this, we'd need to know what you had before, since there is a known bug related to LibreOffice v.7 and JDK on macOS (but the strange this is: The known bug #tdf135479 throws an error about a defective Java environment and not a missing one). See comment #14 in the bug report, which states the JDK 12.0.2 should work. But as above: Due to the differences in error messages and lack of any knowledge of previous version within your installation, I'm not sure, whether the bug applies to you as well.
Looking at my 'DownLoad' folder I suspect that the version of LO prior to the upgrade was 6.3.3. The only version of JDK I can see is JDK-14. Reading the comment #14 it does look as though that might be the problem and it still exists in JDK-15. ColinT
