    Oracle JRE8 HotSpot GC vs OpenJDK GC



      AFAIK, there is a relation between Oracle HotSpot JDK8 VM and OpenJDK. There may be some differences and lags but also synergy between the code bases.


      My question is specifically about the GC implementation in both. How different are the GC and their implementation, or how similar are they?

      Breaking this question into smaller bits:

      - are these the same algorithms?

      - are these the same GC e.g., CMS, G1, etc?

      - are these exact same code bases? or maybe with some minor \ major time differences?
