latest-alpine fails to start due to erroneous shared library search paths for JVM

[norriscm]

In latest-alpine, the Unifi server fails to start because the java executable cannot open libjli.so:

<docker-entrypoint> EXEC - su-exec unifi:unifi /usr/bin/java  -Xmx1024M -Dunifi.datadir=/usr/lib/unifi/data -Dunifi.logdir=/usr/lib/unifi/logs -Dunifi.rundir=/usr/lib/unifi/run -Djava.awt.headless=true -Dfile.encoding=UTF-8 --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.time=ALL-UNNAMED --add-opens java.base/sun.security.util=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED --add-opens java.rmi/sun.rmi.transport=ALL-UNNAMED -jar /usr/lib/unifi/lib/ace.jar start
Error loading shared library libjli.so: No such file or directory (needed by /usr/bin/java)
[various relocation errors for missing symbols]

It appears that the shared library search paths in the container are for the wrong version of OpenJDK. The contents of the musl ld path file in the image are:

/lib
/usr/lib
/usr/local/lib
/usr/lib/jvm/java-1.8-openjdk/jre/lib/amd64
/usr/lib/jvm/java-1.8-openjdk/jre/lib/amd64/jli
/usr/lib/jvm/java-1.8-openjdk/jre/lib/amd64/server

The last three directories do not exist in the container because it uses OpenJDK 17.

I was able to get the container running by executing the following command within the container to fix the library paths:

sed -i -e 's/1\.8/17/' -e 's|/amd64||' -e 5d /etc/ld-musl-x86_64.path
