If we instead look at how the pause times have improved, we can see that there has been some extraordinary work going on in ZGC. Applications of super-mathematics to non-super mathematics. It is still strongly typed, though, and only applies to variablesinside methods(thanks,dpash, for pointing that out again). Lets start with this did the no default warning in switch ever annoy you? Now, historically (pre-Java 8), there were actual source differences between OpenJDK builds and OracleJDK builds, where you could say that OracleJDK was 'better'.
