Chris Goffinet commented on CASSANDRA-3675:
-------------------------------------------
For the record, I still think this is a sane default.
> ship with -XX:+ExplicitGCInvokesConcurrent by default

> It's so much easier if you can safely tell people to trigger a full GC to
> discover their live set (see CASSANDRA-3574), instead of explaining the
> behavior of CMS and what the memory usage graph looks like etc etc. Shipping
> with {{-XX:+ExplicitGCInvokesConcurrent}} means this is by default safe.
> For people that have special needs like some kind of rolling compacting GC
> with disablegossip, they are special enough that they can just change the VM
> options.
