Got it.

Even

openjdk-11 (11.0.3+4-2) unstable; urgency=medium

  [ Matthias Klose ]
  * Configure with vendor flags.
[...]

?

That one is the problem.

Let's compare:

buster has:

$ java -XshowSettings:properties -version 2>&1 | grep vendor
    java.specification.vendor = Oracle Corporation
    java.vendor = Oracle Corporation
    java.vendor.url = http://java.oracle.com/
    java.vendor.url.bug = http://bugreport.java.com/bugreport/
    java.vm.specification.vendor = Oracle Corporation
    java.vm.vendor = Oracle Corporation

sid has:

$ java -XshowSettings:properties -version 2>&1 | grep vendor
    java.specification.vendor = Oracle Corporation
    java.vendor = Debian
    java.vendor.url = https://tracker.debian.org/openjdk-11
    java.vendor.url.bug = https://bugs.debian.org/openjdk-11
    java.vm.specification.vendor = Oracle Corporation
    java.vm.vendor = Debian

Indeed, jvmfwk has a known list of JDKs, and "Debian" (or whatever else
distro) does not appear in it:
https://cgit.freedesktop.org/libreoffice/core/tree/jvmfwk/distributions/OpenOfficeorg/javavendors_linux.xml?h=libreoffice-6-1-5
and it looks in java.vendor:

jvmfwk/plugins/sunmajor/pluginlib/vendorbase.cxx:    //get java.vendor,
java.version, java.home,
jvmfwk/plugins/sunmajor/pluginlib/vendorbase.cxx:        if(! bVendor &&
prop.first == "java.vendor")

Indeed, after adding "Debian" as a copy of "Oracle Corporation" javaldx
works again.

We as distros can patch it for LibreOffice, but this change breaks LibreOffice out there unless
patched, and I doubt they will (or will be happy) to add extra stanzas for "Debian", "Ubuntu" or
whatever else.

I really believe this should be reverted.
