Slackware64 14.2 Java and jvm inconsistent and who created /usr/lib64/jvm?

Today I was updating my Oracle jre with PV's script from /extra. When I checked that AOO had the correct version registered, for the Base program, I also noticed that it found two versions of java. It found Oracle 1.8.0_231 and FSF 1.5.0. Which was odd, because I remember removing openjre a long time ago an it doesn't appear in my /var/log/packages. So I checked "which java", and it points to /usr/lib64/java/bin/java, which is 8u231. But in /usr/lib64 there is also a /usr/lib64/jvm/ which appears might be the old FSF 1.5? It is full of symlinks which piont to ../../../bin/foobarxyz.

So my question is who created /usr/lib64/jvm? Where will I find FSF 1.5.0? Is it included as a default with AOO maybe?

Cheers
