A file list does not tell you everything. You forgot to check two 
things:

(1) A Slackware package also contains a "doinst.sh" script and that is 
where the symbolic links are created when installing the package. 
Some packages may create symbolic links in /usr/bin for binaries that 
are installed to a non-system directory. LibreOffice is one of those. 
The openjdk packages do not create symbolic links in /usr/bin but they 
do so in other places. Finding the java and javac binaries is 
accomplished differently:

(2) The Slackware JDK and JRE packages install profile scripts into 
/etc/profile.d/ . If the user logs in (or starts an X terminal with a 
login session) this profile script will be sourced and this will 
expand several variables so that your Java will work properly: PATH, 
MANPATH and JAVA_HOME.
See below for the content of the profile script for bash-compatible 
shells on a 64bit Slackware computer:

$ cat /etc/profile.d/openjdk.sh
#!/bin/sh
export JAVA_HOME=/usr/lib64/java
export MANPATH="${MANPATH}:${JAVA_HOME}/man"
export PATH="${PATH}:${JAVA_HOME}/bin:${JAVA_HOME}/jre/bin"

If you do not start a login shell you will miss loading important 
other profile scripts as well, not just the openjdk one.

Cheers, Eric
