help needed with LibreOffice Java bridge on armhf

[Rene Engelhard]

Hi,

since LibreOffice 7.6 (which added some more tests which were manual
before to the automatic set) the testtools' bridge test fails:

https://buildd.debian.org/status/fetch.php?pkg=libreoffice&arch=armhf&ver=4%3A7.6.2-5&stamp=1698791231&raw=0

only on armhf. armel and arm64 just work.

it says

(Even though one probably shouldn't do it I did try to build it

- without -fstack-protector-strong -> with just -fstack-protector: fails
the same way

- without -fstack-protector:


Fails in a different way:

So might it be the same failure mode as ppc64/s390x?

See the discussion upstream in
https://lists.freedesktop.org/archives/libreoffice/2023-September/thread.html:
"new bridgetest failures in 7.6 on ppc64le "

(while mentioning ppc64el initially s390x is affected, too)

and continued in October


https://lists.freedesktop.org/archives/libreoffice/2023-October/thread.html

especially
https://lists.freedesktop.org/archives/libreoffice/2023-October/091058.html
and

https://lists.freedesktop.org/archives/libreoffice/2023-October/091059.html


after which unfortunately noting important happened. (And I don't see a
patch either at Fedora git nor submitted upstream to fix this.)

This is probably architecture-specific since the other architectures
*do* work (except ppc64el and s390x).


Can you have a look at it?

(The workaround would be --without-java which I verified to work on my
rpi4, but this opens a can of worms. Not only disabling some (built-in)
features like the Report Builder but especially since there is
Java-based extensions (_all!) which then get into trouble
dependency-wise/LO will be blocked from migrating to testing maybe...)

I needed to do that now :(. It's live now in sid.

It now also makes natbrailles autopkgtest fail[1] since that one of
course wants ure-java which is Out-of-sync and probably should be
decrufted somewhen:

$ rmadison -s unstable ure-java
ure-java | 4:7.5.9~rc1-1 | unstable | armhf, ppc64el, s390x
ure-java | 4:7.6.4~rc1-1 | unstable | amd64, arm64, armel, i386
