Late enhancement approved by Project Lead.

Late Enhancement Request: Justification: this RFE would bring some improvements in the way Java code can interact with off-heap memory; the incubating nature of the RFE will allow the developers to gather feedback on the memory access API, and to make adequate adjustments before the feature is finalized. Estimated integration date: 2019-12-13 RIsk: low, as the API comes in an incubating module, it is disabled by default and requires command-line options to enable it RFR: https://mail.openjdk.java.net/pipermail/core-libs-dev/2019-December/063836.html
