With the latest fix from #8786 (OpenJ9 - ffece8e), locally II don't see the crash with ** ASSERTION FAILED ** at jswalk.c:538: ((0 ))
anymore. But the test still failed in rc001
, rc020
, and ta001
. Not much error message from rc001
and rc020
. ta001
encountered java.lang.IllegalArgumentExceptionjava.lang.IllegalArgumentException

It shows that the failing PC at +35 is not valid, it's off by 1.
The stack trace shows that the stack walk was caused by stack overflow which seems to be caused by the jitted method somehow recursively calling itself.

The code around failing PC may conditionally jump to call to jitReportMethodEnter
so this is the main suspect. It's also suspicious because this crash only appears in tests using Full Speed Debug, and method enter/exit hooks are used for it.
@liqunl could you please specify what's unclear about this crash? I don't think I understand everything entirely. @mpirvu fyi.
The stack is interleaved with JIT frame, JIT resolve frame, JNI call-in frame. The thread seems to be looping between these frames, then we ran out of stack, and ended up in jitStackOverFlow
.
It seemed to me the JIT code called to the VM, but somehow VM called back to the same JIT method. This doesn't look right, unless something happened in VM to cause it to call the NPE constructor.
The return address +35 doesn't point to a valid instruction, the one close to it is +34, but that is not a call, so it shouldn't be the return address either.
+44 may jump to an instruction that calls to jitReportMethodEnter
, so I wonder if the JIT code called out to jitReportMethodEnter.
@gacholio How can I tell what VM is asked to do by the JIT? Anything you can figure out from the files I uploaded?
j9vmthread.txt javacore.txt javavm.txt kca-stack.txt NPE.init.asm.txt NPE.stackslots.txt
I was also able to get a trace file for the failing method.
NPE.log.12237.server.1.txt Note that this file was obtained from a different failing run, so the addresses will not match the ones in the files above.
jitStackOverflow
does not indicate an infinite recursion - it's also used to grow the stack from its initial small size to increasingly larger sizes, which is what appears to be happening here.
From the javacore, the failure is occuring in early thread startup (the fact that the thread is unnamed).
I won't be able to say anything more without a system core to look at.
@dmitry-ten Could you upload the core dump to /team/triage/liqunl/openj9-9024
?
Sure. Where is that folder located?
Uploaded the core dump.
@gacholio The core and JDK is in /team/triage/liqunl/openj9-9024

Based on the above code, I don't see anywhere that could have a JIT PC of 0x00007FCAB10E4283 (1 beyond 0x00007FCAB10E4282 which is at least a valid instruction, likely at bytecode 0).
Based on the PC appearing so many times in the stack, it's not likely to be a patching issue at 0x00007FCAB10E4282. Based on the NOPs, it looks there has been some patching of unresolved calls to the super constructor(s).
The interleaved resolve frames tell me that the recursion is likely occurring at the method enter or exit reporting, which should not be firing as the test does not reserve the capabilities or enable the events.
I suspect this is an issue with JIT server not understanding how the VM is configured. If the VM is not reporting method enter/exit, the so-called "extended method block" is not created, so the code that's querying to see if enter/exit is enabled is reading random memory.
> !j9javavm 0x00007FCAC8013730 |grep runtimeF
0xc8: U32 runtimeFlags = 0x00200022 (2097186)
#define J9_RUNTIME_EXTENDED_METHOD_BLOCK 0x200000
Nope - looks like the block is enabled.
Yeah, JITServer should be correctly checking with the VM if the method enter/exit tracing is enabled. Hook addresses and extended flags pointers should also be retrieved from the VM.
I do see something suspicious - the code is testing the same byte twice for two different method enter checks (and the two exit checks). These bytes should represent the inlined super constructors, so they could not possibly have the same address for the check byte.
That doesn't explain the recursion or the bad JIT PC, but there's something clearly wrong in the codegen here. If this issue is repeatable, I suggest building a debug VM and stepping the code in question to see what the actual sequence of events is.
This is running in forced JDWP mode, so method enter and exit have very likely been hooked, but if the JDWP event handler were firing and calling back in, there would be a JNI callout frame between the JNI callin and resolve frames. The other user of the event is method trace, which does not appear to be enabled, and would not call back to java in any event.
I'm not sure I understand. This is the code that creates the IL tree for the test: https://github.com/eclipse/openj9/blob/40f5a96154580755c3bc252241c17a77c5d6d35a/runtime/compiler/env/VMJ9.cpp#L3237-L3258
0x7fcab10e4282: movzbl -0x769ea1e2(%rip),%ecx # 0x7fca3a6fa0a7
0x7fcab10e4289: test $0x1,%cl
0x7fcab10e428c: jne 0x7fcab10e4349
So it's testing the flag of enter/exit hook. Wouldn't that address be the same for all method enter checks?
Yes, I thought it was doing the optimized version and checking the method itself, so I'm even more mystified than before about what's going on.
If you can provide me something simple to reproduce this on Java 8 then I can step through the VM code and see what's up.
This failure is very intermittent, I can reproduce it in around 1/100 runs.
To start JITServer:
> ~/debug/j2sdk-image/bin/jitserver
To run the test:
> sudo TEST_JDK_HOME=~/debug/j2sdk-image EXTRA_OPTIONS=" -XX:+UseJITServer " make _cmdLineTester_jvmtitests_debug_openj9_none_SCC_3
The problem is that NullPointerException.<init>
doesn't get compiled every run, despite the test running with count=0
.
I tried passing dontInline
to the test, but that doesn't force the compile either. So this makes stepping through the VM code pretty difficult to setup.
Interestingly, so far I haven't seen any compilations of NullPointerException.<init>
in _cmdLineTester_jvmtitests_debug_openj9_none_SCC_3
without JITServer enabled. I've done around 200 runs so far.
Could there be any reasons why JIT shouldn't be compiling that method with FSD enabled?
Does it fail every time that NPE init is compiled? If so, we can use a method selective breakOnEntry
.
I can't think of any reason FSD would prevent the compilation - perhaps the root of the problem is hitting the NPE in the first place. I would not have expected there to be intentional NPEs during the construction of the comparator, though I haven't looked at the bytecodes. It's also annoying that every bcIndex seems to be -1 in the stack.
Yes, it fails every time the constructor is compiled.
How is breakOnEntry
used?
Hm, so if the problem is actually in java/lang/String$CaseInsensitiveComparator.<init>(Ljava/lang/String$1;)V
I should probably trace that method too
breakOnEntry
is specified like any other JIT option - it can be filtered down to the method level. It inserts an int 3
instruction at the start of tagged methods which will stop in gdb/windbg so you can step from then on.
The comparator bytecodes:
> !bytecodes 0x0000000000047BF0
Name: <init>
Signature: (Ljava/lang/String$1;)V
Access Flags (1041000): default synthetic
Max Stack: 1
Argument Count: 2
Temp Count: 0
0 aload0
1 invokespecial 1 java/lang/String$CaseInsensitiveComparator.<init>()V
4 returnFromConstructor
There's exactly one point where NPE could occur there (based on the java stack the call was not inlined), indicating that the receiver was null, which is impossible, particularly since the String static initializer that called this is not compiled (the interpreter will always throw NPE if the receiver of an invokespecial
bytecode is null - all constructor invocations are invokespecial
).
I'm increasingly baffled by what's going on here.
There is a similar issue where we actually get NPE instead of this failure. I wonder if that's related.
That test is also enabling method enter and it's early on in startup so it seems likely to be the same problem.
Looking at sun/reflect/Reflection.getCallerClass
trace, I don't see anything suspicious there either. It calls a method enter hook if tracing is enabled and then jumps to the native method. Since the method is so simple the only thing I can think of that can go wrong is if sometimes the method is not actually traced, but the server thinks it is traced for some reason.
We do caching of which methods are traced on the server, but it's done per client and whenever a class gets unloaded or redefined tracing info of its methods gets deleted too.
There is one suspicious thing that could be related to this issue: From the failing core dump:
0x00007fbd47987282: movzbl 0x4be47c4e(%rip),%ecx # 0x7fbd937ceed7
0x00007fbd47987289: test $0x1,%cl
0x00007fbd4798728c: jne 0x7fbd47987349
0x4be47c4e(%rip)
should be the address of the hook. Based on the comment, 0x4be47c4e(%rip)=0x7fbd937ceed7
.
However 0x7fbd937ceed7
is an invalid address. Either 0x7fbd937ceed7
is not actually the address of the hook, and I misunderstand what it means, or the address of the hook is somehow wrong. But this shouldn't be possible, because JITServer requests it from the client every time, no caching involved.
Why is the address of hook related to rip
? If the offset to rip
is relative to the instruction address in the server VM, and the JIT code got relocated in the client VM, then the offset is wrong.
I'm not sure why it's rip
. In the trace file it's
movzx ecx, byte ptr [$0x00007fb890016367]
The rip
in the instruction should be next instruction's address. I just took a look at the trace log, the offset is relative to the instruction address in the server VM.
We need to change the encoding for JITServer, but I don't know where the encoding for X86 memory reference is done. @0xdaryl May I ask for your help?
If the address is unreadable, I would expect a crash rather than an NPE (NPE is only thrown for crashes in a small region above address 0).
https://github.com/eclipse/omr/pull/5658 fixes JIT stackmap not found crashes in cmdLineTester_jvmtitests_debug_openj9_none_SCC
tests but now I see a NPE always being thrown in cmdLineTester_jvmtitests
. So I'm continuing to investigate this issue. It's possible that fixing one problem just exposed another.
This should finally be fixed by eclipse/omr#5658. I'll run tests in Grinder and verify that the problem is gone, then the issue can be closed.
@mpirvu, a run of 200 tests timed out due to each test taking too long. But out of 82 tests run, all passed, so this can probably be closed.
Fixed by https://github.com/eclipse/omr/pull/5658 Closing based on the previous message.
