Description

I was testing out the 2.23.2 release with WildFly-Camel and our camel-leveldb integration test has started to fail with:

java.lang.NoClassDefFoundError: org/fusesource/leveldbjni/JniDBFactory

I think the changes introduced in CAMEL-13368 have caused this. Specifically the static import for the factory class:

https://github.com/apache/camel/blob/camel-2.23.x/components/camel-leveldb/src/main/java/org/apache/camel/component/leveldb/LevelDBFile.java#L36

There's a dedicated private getFactory() method in LevelDBFile, which is more friendly for modular class loading environments. So I think the code should be using that instead.
