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
