What is the current stance of Elastic on large heaps, ES 6.2.4 with G1GC? Is it still not recommended? Thank you ---

6.5.0 will support G1GC, see [Is now possible to use G1GC with ES 6.4.x](https://discuss.elastic.co/t/is-now-possible-to-use-g1gc-with-es-6-4-x/150681) ---

I want to clarify something here. We _intend_ that 6.5.0 will support G1GC when run on JDK 10. However, nothing is guaranteed until we actually release. ---
