Currently Cache store properties may get changed according to the naming strategy, while they shouldn't. See link to source code.

As an example, with RocksDB store property 

<property name="data.write_buffer_size">64MB</property> the underscores get converted to dashes, as a result RocksDB will complain about an unknown property.

Note the dashes in error message: 

org.infinispan.commons.CacheConfigurationException: ISPN000294: RocksDB properties {write-buffer-size=64MB}, contains an unknown property
