Many applications in Alibaba are written in Java with a billion lines of code. Alibaba's investment in OpenJDK dated back to 2010. Alibaba Dragonwell, is a downstream of OpenJDK, and customized to meet the needs of rapidly growing business of the Alibaba ecosystem.  RISC-V, as an open source architecture, is the new exciting area in computer architecture and is gaining more attractions.   By collaborating with communities, we are investigating the port work of OpenJDK on RISC-V. In this talk, we will describe the current status of port development on OpenJDK for RISC-V architecture, and the combability and performance issues while running the full Java application on RISC-V with OpenJDK.   The suggested agenda is as follows: -    Introduction to the Alibaba Java usage on RISC-V -    Current status of JDK port work -    Evaluation of popular java frameworks on RISC-V with OpenJDK -    Performance optimization for SPECjbb2015 -    Comparison between RISC-V and ARM  We still see the gap between the current work and the final version ready for productions. While the experience we learned during porting process could be useful to the community.
