49c3c35a14 8038422: CDS test failed: assert((size % os::vm_allocation_granularity()) == 0) failed when limiting SharedMiscDataSize 
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.

7ade7987a0 8007074: SIGSEGV at ParMarkBitMap::verify_clear() 
Replace the broken large pages implementation on Linux. New flag: -XX:+UseTransparentHugePages - Linux specific flag to turn on transparent huge page hinting with madvise(..., MAP_HUGETLB). Changed behavior: -XX:+UseLargePages - tries to use -XX:+UseTransparentHugePages before trying other large pages implementations (on Linux). Changed behavior: -XX:+UseHugeTLBFS - Use upfront allocation of Large Pages instead of using the broken implementation to dynamically committing large pages. Changed behavior: -XX:LargePageSizeInBytes - Turned off the ability to use this flag on Linux and provides warning to user if set to a value different than the OS chosen large page size. Changed behavior: Setting no large page size - Now defaults to use -XX:UseTransparentHugePages if the OS supports it. Previously, -XX:+UseHugeTLBFS was chosen if the OS was configured to use large pages.
