Greetings,
Recent testing has revealed an issue with the following fix:
JDK-8200235 Generalize jniFastGetField jobject/jweak resolve https://bugs.openjdk.java.net/browse/JDK-8200235
The following bug is tracking the new failure mode:
JDK-8202381 (Solaris) SIGBUS in # V [libjvm.so+0xcee494] jni_GetIntField+0x224 https://bugs.openjdk.java.net/browse/JDK-8202381
The following bug is being used to backout the fix for JDK-8200235:
JDK-8202386 [BACKOUT] fix for 8200235 https://bugs.openjdk.java.net/browse/JDK-8202386
Here's the backout webrev:

The backout was generated by:
$ hg log -v -r 4745598b307f changeset: 49898:4745598b307f user: eosterlund date: Thu Apr 26 11:56:24 2018 +0200 files: src/hotspot/cpu/aarch64/gc/shared/barrierSetAssembler_aarch64.cpp src/hotspot/cpu/aarch64/gc/shared/barrierSetAssembler_aarch64.hpp src/hotspot/cpu/aarch64/jniFastGetField_aarch64.cpp src/hotspot/cpu/sparc/gc/shared/barrierSetAssembler_sparc.cpp src/hotspot/cpu/sparc/gc/shared/barrierSetAssembler_sparc.hpp src/hotspot/cpu/sparc/jniFastGetField_sparc.cpp src/hotspot/cpu/x86/gc/shared/barrierSetAssembler_x86.cpp src/hotspot/cpu/x86/gc/shared/barrierSetAssembler_x86.hpp src/hotspot/cpu/x86/jniFastGetField_x86_64.cpp description: 8200235: Generalize jniFastGetField jobject/jweak resolve Reviewed-by: kbarrett, dholmes

I sanity checked the backout with:
$ hg diff -r 49897 cat file.list | wc
0 0 0
which compares the changeset before 49898:4745598b307f with the current tip. All is good.
