Suggested fix: do not unmap the jimage. Let the OS deal with resource deallocation.
18-03-2021
From 3 out of the 4 openjdk-1?-jimage-stacktrace_thread-stacktrace.txt files in the attachments of this bug, we can see that there is native library code calling the C library's exit handler, which causes destruction of the ImageFileReader::_reader_table in imageFile.cpp, which unmaps the image file. Current Java threads are still running, and they crash when trying to load a class from the image: $ egrep '^((#)|(Thread ))' openjdk-11-jimage-stacktrace_thread-stacktrace.txt | sed -e 's/[(].*//g' | less Thread 26 #0 0x00007fd64757dc44 in _fini #1 0x00007fd6f54bbb93 in ?? #2 0x00007fd6f4eec041 in __run_exit_handlers #3 0x00007fd6f4eec13a in __GI_exit #4 0x00007fd6a6a939a8 in _XIOError #5 0x00007fd6a6a91a81 in _XReply #6 0x00007fd6a6a8d1cd in XSync $ egrep '^((#)|(Thread ))' openjdk-13-jimage-stacktrace_thread-stacktrace.txt | sed -e 's/[(].*//g' | less Thread 33 #0 0x00007f4c52dbefe0 in __do_global_dtors_aux <---- global destructor #1 0x00007f4d1be8af5b in ?? $ egrep '^((#)|(Thread ))' openjdk-15-jimage-stacktrace_thread-stacktrace.txt | sed -e 's/[(].*//g' | less Thread 8 #0 ResourceHashtable<unsigned char*, decode_env::SourceFileInfo, &decode_env::SourceFileInfo::hash, &decode_env::SourceFileInfo::equals, 15889u, #1 0x00007fdeedde6a57 in __run_exit_handlers #2 0x00007fdeedde6c00 in __GI_exit #3 0x00007fdeec67bd9e in forceExit #4 0x00007fdeec67835d in doExit #5 0x00007fdeec67ed69 in debugLoop_run #6 0x00007fdeec691f89 in connectionInitiated #7 0x00007fdeec692258 in attachThread #8 0x00007fdeed48ad57 in JvmtiAgentThread::call_start_function #9 0x00007fdeed8b73ce in JavaThread::thread_main_inner

Agree. Since we only have one jimage per JVM and the JVM does not expect to be relaunched in a give app. 1. Eliminate the image table of open files and track with a single element. 2. Never allow the closure of a jimage, preventing the unmapping of the file. 3. Eliminate the recounting of opens.

Thanks David. This is brilliant.

The ImageFileReaderTable is a static and so its destructor will be called at process exit time, and that will close/delete the image file. Normal VM termination mechanism take the VM to a safepoint so no further use of the image can be in progress, but the gtests, and potentially other native applications using the VM could call exit() directly and so encounter this problem. See also: JDK-8244744, JDK-8261916.

Although it is filed under "jlink", this is actually a jimage runtime issue. That native code does not share anything with jlink code.
16-12-2020
Reports have it consistently failing at ImageFIle.cpp:88 s4 value = endian->get(redirect[index]); My thought is that 'redirect' is pointing to invalid memory. 'redirect' should be pointing into the middle of the memory mapped jimage directory. So I think the jimage is failing to memory map. This could be due to a lot of things but other memory mapping might be dislodging the jimage.

Ubuntu automatic crash report is still saving reports of this issue. I can provide more hs_err logs and stacktraces if necessary. The most recent versions that I have reports for are 11.0.9, 13.0.4, 14.0.2, 15b36. Please not that only OpenJDK 11 is available on Ubuntu stable releases, thus we don't get as many reports for 13, 14, and 15 as they are available only our "devel" release or a short release. The versions 13.0.5, 15.0.1, and 16b14 have not yet been published, so we have not got any reports on them (yet). I am sorry to say that I do not have a proper reproducer, but I might be able to get a core file - as it might contain private user information, I would need to double check with my manager how we could go about it.

I see a lot of similar crashes in OpenJDK from Ubuntu. First started appearing in 10.0.1+10 and for some reason the number of crashes reduced significantly after 11.0.6+10, but it is still showing up even on 11.0.8+10. Also shows up on OpenJDK 13 and 14.

It's the second time. The first time it was called with an empty string so StringLatin1 is used only during the second call. public int hashCode() { int h = hash; if (h == 0 && value.length > 0) { hash = h = isLatin1() ? StringLatin1.hashCode(value) : StringUTF16.hashCode(value); } return h; } # Use a debug build of java: $ java -Xshare:off -XX:+TraceBytecodes -Xlog:class+load -version > x.x $ egrep -n '(String.hashCode)|(StringLatin1)' x.x | head -4 4713:[7728] virtual jint java.lang.String.hashCode() 4737:[7728] virtual jint java.lang.String.hashCode() 4741:[7728] 3515 29 invokestatic 85 <java/lang/StringLatin1.hashCode([B)I> 4742:[0.211s][info][class,load] java.lang.StringLatin1 source: jrt:/java.base

Thank you Ioi. Since I have you here. :-) Is it the first time String.hashCode was called?

Gerard's crash happened before the module system has been fully started, so all loaded classes were loaded by the bootstrap class loader. If you run "java -XX:+TraceBytecodes -Xshare:off -verbose -version" with a debug JVM, it prints out all the classes that are being loaded. Classes up to "java.lang.ArithmeticException" (about 119-th loaded class) are loaded directly by the VM, without execute any Java code. All of the remaining classes are loaded as part of executing Java code (e.g., a Java bytecode refers to a class that has not been loaded yet). "java.lang.StringLatin1" is loaded as around the 161-th class (as the result of executing String.hashCode()). In Gerard's crash, this loading attempt failed. So the call path from SystemDictionary::resolve_or_fail ... ImageStrings::find would have succeeded for more than 40 times, all while running some sort of Java code, before the failure happened.

Those are loaded by the native system loader. Thinking String::hashCode is the first loaded on the Java side.

Re: Could String::hashCode be the first method loaded by Java code? That doesn't seem to be the case from the Java call stack. We are several levels deep in Java calls, and ConcurrentHashMap is definitely loaded when executing Java code (because it's not in the list of well-known classes loaded early in native code during HotSpot bootstrap). j java.lang.String.hashCode()I+29 java.base j java.util.concurrent.ConcurrentHashMap.putVal(Ljava/lang/Object;Ljava/lang/Object;Z)Ljava/lang/Object;+17 java.base j java.util.concurrent.ConcurrentHashMap.put(Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;+4 java.base j java.util.Properties.put(Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;+6 java.base v ~StubRoutines::call_stub j java.lang.System.initProperties(Ljava/util/Properties;)Ljava/util/Properties;+0 java.base j java.lang.System.initPhase1()V+15 java.base v ~StubRoutines::call_stub

Deferring due to lack of reproducibility.

Going to be difficult to reproduce. Srini tried running several times on Mach5 and could not reproduce (extreme rareness.) Wish there was a common thread. Could String::hashCode be the first method loaded by Java code? Prior to this point classes have been loaded natively? Is jimage opened by the native code not fully initialized when the Java code goes to use it?

I thought that was a run with CDS enabled ON by default, but I was wrong.
05-12-2018
After some archaeological work, I found the hs_err file for Gerard's crash (hs_err_pid433.log in attachments). The version string also indicates that CDS is not enabled. # Java VM: Java HotSpot(TM) 64-Bit Server VM (fastdebug 12-internal+0-2018-07-30-1814111.gerard.ziemski.jdk12baseline, mixed mode, tiered, compressed oops, concurrent mark sweep gc, linux-amd64) What's interesting in hs_err_pid433.log, as well as hs_err_pid16585.log in a similar crash in JDK-8207138, the hs_err file is cut off. Looks like the JVM has trouble writing the hs_err file.

What is puzzling is that to come to the crash at String.hashCode(), many classes (about 160) would have already been successfully loaded from the jimage. So why would those have succeeded but java/lang/StringLatin1 causes an crash? Perhaps looking at the location of this class (or its index) might give some clues.

Regarding the question whether this bug might be related to CDS. I think the answer is no. So far we have observed 2 crashes: [1] The original crash in the bug description is not using CDS, or else you'd see "shared" in the version string. # Java VM: Java HotSpot(TM) Server VM (9-internal+0-2016-09-23-203306.amurillo.jdk9-hs-2016-09-19-snapshot, mixed mode, tiered, g1 gc, windows-x86) [2] The new crash reported by Gerard on 2018-07-31 crashes when resolving a constantpool entry while executing java.lang.String.hashCode(). I cannot access the test results anymore, but here's my evaluation from the available information.

If running with CDS enabled, this class would be loaded from the CDS archive. However, the C call stack above indicates that the class is not loaded from the CDS archive, and we're trying to load it from the JIMAGE instead. This indicates a strong possibility that CDS is not enabled.

I asked because Gerard said he was using CDS (obviously wasn't) and JDK-8207138 was using Graal.
05-12-2018
This problem was seen just once during VM PIT last week. I don't have another result.

Can you give be a fail with a fastdebug build?
