Type is the JPL type (a ground term) denoting the same Java type as EntityName does.

The Java type in question may be a reference type (class, abstract class, interface), and array type or a primitive, including "void".

Examples:

int                       int
integer                   class([],[integer])
void                      void
char                      char
double                    double
[D                        array(double)
[[I                       array(array(int))
java.lang.String          class([java,lang],['String'])
[Ljava.lang.String;       array(class([java,lang],['String']))
[[Ljava.lang.String;      array(array(class([java, lang], ['String'])))
[[[Ljava.util.Calendar;   array(array(array(class([java,util],['Calendar']))))
foo.bar.Bling$Blong       class([foo,bar],['Bling','Blong'])

NB uses caches where the class has already been mapped once before.
