Description Jean-Louis Dupond 2020-09-09 11:30:34 UTC

Description of problem:
When you install ovirt-engine-extension-logger-log4j on CentOS8, it creates a symlink:
/usr/share/ovirt-engine-extension-logger-log4j/modules/org/ovirt/engine/extension/logger/log4j/main/log4j.jar


lrwxrwxrwx. 1 root root  25 Mar 25 09:21 log4j.jar -> /usr/share/java/log4j.jar

The issue here is that /usr/share/java/log4j.jar does not exist on CentOS8!
log4j12 contains:
# rpm -ql log4j12-1.2.17-22.module_el8.0.0+30+832da3a1.noarch
/usr/share/java/log4j-1.2.17.jar
/usr/share/java/log4j-1.jar
/usr/share/java/log4j12-1.2.17.jar

So the extension fails to load.
Fixed this by adjusting the symlink, but it should be clean in the package.

Comment 1 Martin Perina 2020-09-10 15:23:09 UTC

Unfortunately we have missed this changed between EL7 and EL8, the workaround is quite simple:

  cd /usr/share/java
  ln -s log4j-1.jar log4j.jar

The issue will be fixed in oVirt 4.4.3 release
