> Currently, Hive assumes that the system class loader is instance of {{URLClassLoader}}. In Java 11 this is not the case. There are a few (unresolved) JIRAs about specific occurrences of {{URLClassLoader}} (e.g. [HIVE-21237|https://issues.apache.org/jira/browse/HIVE-21237], [HIVE-17909|https://issues.apache.org/jira/browse/HIVE-17909]), but no _"remove all occurrences"_. Also I couldn't find umbrella "Java 11 upgrade" JIRA.
> This ticket is to remove all unconditional casts of any random class loader to {{URLClassLoader}}.
