It breaks "NULL in last_sp" invariant of top frame in non-fatal way, making it visible only in debug builds.
And this part is rewritten in jdk9 when JVMCI introduced. Starging with 9, everything restored prior checking for exception. 8 is trying to restore as little as possible before checking for exception and going to handler.
The 8's non-exceptional path of is OK.

PS. I have no push rights, so I ask someone to push

Thanks,
