A DESCRIPTION OF THE PROBLEM :
When executing a test program on OpenJDK 8 with the "-XX:-ReduceBulkZeroing" option enabled, incorrect results are observed. However, if the "-XX:-ReduceBulkZeroing" option is removed, the test program runs normally and produces the expected output.

This bug is specific to OpenJDK 8 and does not affect other versions of the JDK.

The test program can be found at : 

https://drive.google.com/file/d/1BaMa2lFOlYg9JpD6ILAEYjEFsOQ-pOrg/view?usp=sharing

**Expected Behavior:**

The test program should execute normally and output “Finish”.

**Observed Behavior:**

The test program produces wrong results, and output:

```
        Test m2 failed
        source: 
        byte TestInstanceCloneUtils$D.i1 = 0
        short TestInstanceCloneUtils$D.i2 = 1
        long TestInstanceCloneUtils$D.i3 = 2
        int TestInstanceCloneUtils$D.i4 = 3
        int TestInstanceCloneUtils$D.i5 = 4
        result: 
        0
        Finish
```

REGRESSION : Last worked in version 11.0.22
