Description
A DESCRIPTION OF THE PROBLEM :
Please see discussion there:
http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2018-November/031364.html

For reference, this is what is posted in first message there:
-----------------------------------------------------------
I'm currently investigating a strange JVM problem and decided to ask 
here in hopes someone already saw such problem, or is able to provide clues.

One of our customers report that our java application crashes often for him.
I did quite a bit of debugging and got some facts:
1) Customer used Windows JRE x64 versions 8.0_144-b01, 10.0.1+10, 
11.0.1+13-LTS. All of them crash with the same symptoms.
2) It crashes because java's NMethod executes a wild jmp, resulting in 
crazy RIP values such as 0xffffffff94bf7f80.
3) Example of corrupted jmp:
    00000000`042b2ac0 e9bb549490      jmp     ffffffff`94bf7f80
4) I managed to understand that correct jmp should be:
    00000000`042b2ac0 e9bb5494ff      jmp     00000000`03bf7f80
5) Correct jmp address points to 'RuntimeStub: wrong_method_stub'
6) Just one byte of jmp instruction is corrupted with 0x90. It's always 
0x90, and always the same byte is corrupted.
7) The crash occurs soon after jvm compiles a new NMethod for the same 
Method.
8) The new NMethod is compiled with new optimization settings, usually 
(but not always) it's 'CompLevel_full_profile' --> 
'CompLevel_full_optimization'.
9) The crash always occurs in the old NMethod.
10) The reason why 'jmp' is there is because old NMethod was 
transitioned into 'non_entrant' state by 'nmethod::make_not_entrant()'
11) Customer says he doesn't have any java-specific tools installed such 
as profilers, etc.
12) Customer provided around 20 crash logs and around 10 crash core 
dumps. This is just a portion of his crashes. All of them exhibit the 
same problem.
13) Customer used Windows RAM test and it shown no errors. On the other 
hand, error is too specific to be a hardware problem, I think: the last 
byte of jmp gets corrupted with 0x90 when a new NMethod is compiled...
14) I have verified customer's jvm.dll and it's not corrupted.
15) I have verified (using core dump) the value of 
'SharedRuntime::get_handle_wrong_method_stub()' and it's not corrupted.
16) In every core dump, only a single NMethod is corrupted.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Happens often for one of our customers.
We don't know how to reproduce it in our environment.


FREQUENCY : often

Summary: "The act of one processor writing data into the currently executing code segment of a second processor with the intent of having the second processor execute that data as code is called cross-modifying code." [1] There are several places in Hotspot where we perform cross-modification of code in an *unsychronized* fashion (listed by John in JDK-8081782): (1) Updating of Inline Caches (2) Patching verified entry when converting nmethod to non-entrant (3) Patching C1 compiled code For above cases it's okay if some other threads still see unpatched values. For example, when hitting an uncommon trap: While the nmethod might still be executed by other threads, we atomically patch the entry point such that it points to `SharedRuntime::get_handle_wrong_method_stub()` (see `nmethod::make_not_entrant_or_zombie()`). It's fine for other threads to miss that update and continue execution, they will eventually hit the uncommon trap as well. However, this assumes that although the update might be missed by other threads, it's still safe, i.e., a thread either sees the old value or the new value. Now several (also recent) Intel processors are affected by an issue named "Unsynchronized Cross-Modifying Code Operations Can Cause Unexpected Instruction Execution Results" that can lead to "unexpected or unpredictable execution behavior" [2]. This means that (1) - (3) can lead to undefined behavior and this is what happens in the case reported by this bug: we crash due to unsychronized nmethod entry patching (2). Cases (1) and (2) will be addressed by the "New Invoke Bindings" JEP (JDK-8221828). I'll therefore close this issue as duplicate. The problem with case (3) remains (although it was never reported), I've filed JDK-8223613 to address this.

ILW = crash due to corrupted codegen; rare, intermittent; possibly disable compilation of identified method! = HLM = P3 (Targeting to 12 for now. We may need to monitor for other any similar cases with reproducible test)

So far just one user reports it and it is not known if it happens for others. I'm not sure whether OS is up to date. User is a bit busy at the moment, so I try to not bother him with lots of questions. He already did a heroic job of answering some preliminary questions, configuring core dumps, reproducing, delivering dumps to us. I took "Windows 7" from hs_err.log file. ----------------------------------------------------------- ----------------------------------------------------------- # # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0xffffffff94bf7f80, pid=4540, tid=4544 # # JRE version: Java(TM) SE Runtime Environment (11.0.1+13) (build 11.0.1+13-LTS) # Java VM: Java HotSpot(TM) 64-Bit Server VM (11.0.1+13-LTS, mixed mode, tiered, compressed oops, g1 gc, windows-amd64) # Problematic frame: # C 0xffffffff94bf7f80 # # Core dump will be written.
