J-NVM is a framework to efficiently access Non-Volatile Main Memory (NVMM) in Java. J-NVM offers a natural interface to persist plain Java objects using failure-atomic blocks. This interface relies internally on proxy objects that intermediate direct off-heap access to NVMM.

J-NVM is a Java framework to efficiently and natively access Non-Volatile Main Memory (NVMM) in Java as off-heap memory.

These key ideas are implemented in the J-NVM framework [7], a lightweight pure-Java library that runs on the Hotspot 8 JVM with the minimal addition of three NVMM-specific instructions (pwb, pfence and psync [5]). J-NVM is a low-level interface that focuses on efficient proxy and memory manipulation. Namely, the bare logic
