> The EntityCoMention engine can throw NPE on several different locations of some of the processed Enhancements do not have fise:confidence values.
> Here an example exception:
> org.apache.stanbol.enhancer.jobmanager.event.impl.EventJobManagerImpl Reported Exception: java.lang.NullPointerException
>     at java.lang.Double.compareTo(Double.java:950)
>     at org.apache.stanbol.enhancer.engines.entitycomention.EntityCoMentionEngine.writeComentions(EntityCoMentionEngine.java:475)
>     at org.apache.stanbol.enhancer.engines.entitycomention.EntityCoMentionEngine.computeEnhancements(EntityCoMentionEngine.java:318)
>     at org.apache.stanbol.enhancer.jobmanager.event.impl.EnhancementJobHandler.processEvent(EnhancementJobHandler.java:271)
>     [...]
> To fix this all calls to Double.compareTo(..) need to ensure that the parsed value MUST NOT be NULL
