So my mistake for not including the FULL source but I did discover
something. The actual code that doesn't work isn't with the
Map<String, Object> but with the @SearchableBoostProperty on the
getter. This is an annotation we use for Compass/Lucene to boost/
score a document higher. The defaultValue property on that annotation
is set to 1.0f and appears to be the cause of the
SerializationException. Removing that annotation eliminates the
Serialization issues we are experiencing but doesn't solve the over
all issue since we need that annotation.
@SpaceExclude()
@SearchableBoostProperty()
public float getRank()
{
Float f = (Float) properties.get("rank");
return ( f == null ? 1.0f : f.floatValue );
}
