b8276670c2 8014765: VM exits if MaxTenuringThreshold is set below the default InitialTenuringThreshold, and InitialTenuringThreshold is not set 
The VM exits when the condition in the subject line applies. The fix sets InitialTenuringThreshold to MaxTenuringThreshold if it is larger than MaxTenuringThreshold and InitialTenuringThreshold has not been set (is default).

c38f8fc543 7176479: G1: JVM crashes on T5-8 system with 1.5 TB heap 
Refactor G1's hot card cache and card counts table into their own files. Simplify the card counts table, including removing the encoding of the card index in each entry. The card counts table now has a 1:1 correspondence with the cards spanned by heap. Space for the card counts table is reserved from virtual memory (rather than C heap) during JVM startup and is committed/expanded when the heap is expanded. Changes were also reviewed-by Vitaly Davidovich.

bb5bd507d7 7112912: Message "Error occurred during initialization of VM" on boxes with lots of RAM 
Ergonomics now also takes available virtual memory into account when deciding for a heap size. The helper method to determine the maximum allocatable memory block now uses the appropriate OS specific calls to retrieve available virtual memory for the java process. In 32 bit environments this method now also searches for the maximum actually reservable amount of memory. Merge previously separate implementations for Linux/BSD/Solaris into a single method.
