scilab does not start (bionic)

[Dima]

1,2) See the apport attachment
3) An appearing of scilab GUI
4) The GUI does not appear.
The command line output:
"
user@user:~$ scilab
/usr/bin/scilab-bin: error while loading shared libraries: libjava.so: cannot open shared object file: No such file or directory
user@user:~$
"

I have the package with libjava.so installed, but it can't find that file anyway.

"
user@user:~$ apt-file find libjava.so
openjdk-11-jre-headless: /usr/lib/jvm/java-11-openjdk-amd64/lib/libjava.so
user@user:~$ apt list openjdk-11-jre-headless
Listing... Done
openjdk-11-jre-headless/bionic,now 10.0.1+10-3ubuntu1 amd64 [installed,automatic]
user@user:~$
"

According to strace output scilab tries to find the file in this location:
/usr/lib/jvm/java-11-openjdk-amd64/lib/amd64/libjava.so
instead of this
/usr/lib/jvm/java-11-openjdk-amd64/lib/libjava.so
