RFR(S): 8200078: [Graal] runtime/appcds/GraalWithLimitedMetaspace.java crashes in visit_all_interfaces

[mikhailo]

The test portion looks good to me.

I have one question - are you able to reliably reproduce this issue 
using GraalWithLimitedMetaspace.java or MaxMetaspaceSize.java ?


Thank you,

Misha
