Trying to track down an issue I am seeing with Solr 8.5.1 running on CentOS
8.2 and Java 14.0.1 (openJDK). My test system was running fine before
updating the OS packages and rebooting at which time it started throwing
the following error:

After tracking down the RPM package likely to cause this issue it was
determined that updating tzdata-java from version 2019c to 2020a causes
this issue. I rolled back that one RPM to the previous version and now the
core loads on startup once again.
So I am trying to determine where or what the issue may be. Is it a Java
issue? Is it a Solr issue? Solr itself starts fine if there are no cores
and the tzdata-java is 2020a. Any suggestions or hints to go on?
Thanks
