8024669: Native OOME when allocating after changes to maximum heap supporting Coops sizing on sparcv9 Summary: After changes in 8010722 the ergonomics for calculating the size of the heap that supports zero based compressed oops changed. This lead to the VM actually using zero based compressed oops. Due to low default HeapBaseMinAddress, the OS mapping in the application image at the same address, and limitations of the malloc implementation on Solaris this resulted in very little C heap available for the VM. So the VM immediately gives a native OOME when the machine has lots of physical memory (>=32G). The solution is to increase the HeapBaseMinAddress so that the VM has enough C heap.
