JDK-6273675 - CompositeData equals & hashCode javadoc differs from CompositeDataSupport equals & hashCode
Description
If you call cd1.equals(cd2), where cd1 is a CompositeDataSupport and cd2 is an object implementing CompositeData (e.g. another CompositeDataSupport), and if cd1 and cd2 have the same CompositeType that includes at least one item of type ArrayType, then the contents of each such array should be compared element by element.  Currently only the array identities are compared, which means that equals returns true if the two objects refer to the same array but not if they refer to different arrays with the same contents.
