Hello Gerber,
.oracle_jre_usage stands for Oracle,
Java SE
Runtime
Environment Usage and is just a Java Usage Tracker related folder.
You can read more here: https://docs.oracle.com/javacomponents/usage-tracker/overview/
It collects data about Java works and whether you want that to happen or not is an entirely different discussion you should have with Oracle.
Conclusion, it's safe to use if you want it.
