/**
* Hacky method of muting the noisy logging from certain libraries.
*
* Normally in ODC we'd rely on the jul-to-slf4j bridge and then configuration of the SLF4J logging backend, but
* we shouldn't make assumptions about the backend within Gradle, and Gradle has its own logging bridges;
* so all we can really do is adjust java.util.logging configuration directly
