**Describe the bug**

I'm getting error running unit tests:

I believe the issue is due to the `jackson-core` in `webjars-locator-core` is overriding its version for everything else:

Per https://fasterxml.github.io/jackson-core/javadoc/2.12/com/fasterxml/jackson/core/util/JacksonFeature.html, `JacksonFeature` is added in 2.12.0, which is newer than the version in `webjars-locator-core`.



Fix is to update `webjars-locator-core` to 0.48.0.
