RFR 8050964: OptimisticTypesPersistence.java should use java.util.Date instead of java.sql.Date

[A. Sundararajan]

Please review http://cr.openjdk.java.net/~sundar/8050964/
Added test (using jdeps) to assert that we don't use non-Compact1 
classes in nashorn.

PS. Piggybacking three recent sample scripts.

Thanks
