Fixes#57
The usage of TableMetricsObjectName-yada-yada relies on translating the
"fake" objectname to a canonical one on remote
publication/serialization. However, the implementation of
ObjectName.getInstance has changed in JDK (micro) updates so it no
longer applies overridable methods -> wrong name published.
Fix by doing explicit ObjectName instansiation.
