8038422: CDS test failed: assert((size % os::vm_allocation_granularity()) == 0) failed when limiting SharedMiscDataSize Summary: In debug version, the assert is against os::vm_allocation_granularity(), but in initialization, we use os::vm_page_size() to align the allocation size. In windows, _vm_page_size and _vm_allocation_granularity may not be same.
