Description
The following test failed in the 2017-07-21 JDK10-hs nightly:

compiler/ciReplay/TestSAServer.java
    Test failed due to "sun.jvm.hotspot.types.WrongTypeException: field
    "_stack_traversal_mark" in type nmethod is not of C integer type, but
    instead of type jlong" on Linux-AArch64 64-bit Server VM, Linux-X64
    64-bit Server VM, Linux-X64 32-bit Server VM, and Solaris SPARCv9
    64-bit Server VM.

    Looks like the _stack_traversal_mark was recently touched by this
    changeset:

    $ hg annot src/share/vm/code/nmethod.hpp | grep 'volatile jlong'
    13298:   volatile jlong _stack_traversal_mark;

    $ hg annot src/share/vm/runtime/vmStructs.cpp | grep '_stack_traversal_mark'
    13298:   volatile_nonstatic_field(nmethod,            _stack_traversal_mark,                         jlong)                                 \

    $ hg log -r 13298

Roman, can you take a look at this test failure: hotspot/test/compiler/ciReplay/TestSAServer.java It appears to be failing due to your changes to JDK-8180932.

Moving from hotspot/svc -> hotspot/runtime since it looks like this is a regression caused by JDK-8180932.
