Description

When built on Java 8 and unit tests are run on Java 11, TestCellUtil fails. A sample stacktrace:

 Tests run: 10, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 2.096 s <<< FAILURE! - in org.apache.hadoop.hbase.TestCellUtil
testGetType(org.apache.hadoop.hbase.TestCellUtil) Time elapsed: 0.544 s <<< ERROR!
org.mockito.exceptions.base.MockitoException:

Cannot call abstract real method on java object!
Calling real methods is only possible when mocking non abstract method.
//correct example:
when(mockOfConcreteClass.nonAbstractMethod()).thenCallRealMethod();
at org.apache.hadoop.hbase.TestCellUtil.testGetType(TestCellUtil.java:543)
