Hi @jaikiran , 

I will spend some time over it, current jtreg tests are unable to detect it. This is information Aditi gave me regarding the failure in OpenJ9: `In openj9 the write is happening but it is corrupting the header bytes added by OMR. And the failure is thrown by OMR when it validates the memory segment.`
