@Matthew Sharp i am not sure if this is dictated by HWX. it goes by Java support for G1. According to the documentation found here, G1 support is on Java 7 Update 9 or later

With the default being CMS there typically is a "certification" process to vet larger changes (similar to supported databases with versions or replication, etc.). The change itself is easy enough the larger concern was around if others have tested/run production clusters with it.

@Matthew Sharp Respectfully I disagree. Please take a look at this post. However I do believe it is not supported at this time.
