Widen a Java wrapper object to a specified primitive type. For example a Short wrapper will be widened to an Integer if the type class represents the primitive int type.

Parameters:

value - The Java wrapper object to widen.

type - the target primitive Java type.

Returns:

possibly a new Java wrapper object with the same value.

Throws:

IllegalArgumentException - if the value is incompatible with the type.
