Request for review(XS): 6996136: VM crash in src/share/vm/runtime/virtualspace.cpp:424

Igor,

Could you consolidate code which set UseCompressedOops in one separate method?
Also we should print warning id user specified COOP:

     if (UseCompressedOops && FLAG_IS_CMDLINE(UseCompressedOops)) {
       warning("Can not use Compressed Oops with shared spaces");
       FLAG_SET_DEFAULT(UseCompressedOops, false);
     }

Thanks,
Vladimir
