    Description

      Between metrics1 and mertrics2 EventCounter was moved from o.a.h.log to o.a.h.metrics.jvm.
      On 0.20-security a wrapper marked with @Deprecated was added back to o.a.h.log for compatibility, the same wrapper exists on trunk, but no on 0.22.

      Without it the TT will fail to start with a ClassNotFoundException.
      Hive configuration also point to this class in the log4j.properties.
