> Arm64v8 supports unaligned access .
> But UnsafeAvailChecker returns false due to a JDK bug.
> The false of UnsafeAvailChecker return also causes the HBase Unit tests(FuzzyRowFilter,
TestFuzzyRowFilterEndToEnd, TestFuzzyRowAndColumnRangeFilter) failures. 
> Enable Arm64 unaligned support by providing a hard-code workaround for the JDK bug.
