RFR: 8227068: [Graal] MappedByteBuffer bulk access memory failures are not handled gracefully

[Jamsheed]

Hi Vladimir,

i have both jvmci + graal changes  here. so i am not very clear on how 
to do it easily. upstream PR will require JVMCI changes to be there 
first right ?

Best regards,

Jamsheed
