solve/debug JVM 崩溃的最佳方法 (SIGSEGV)
Best way on how to solve/debug JVM crash (SIGSEGV)
我真的很迷茫，我不知道如何去面对和解决我的问题。我有一段简单的 Java 代码，导致 JVM 崩溃：
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00000001057ce9d4, pid=10727, tid=18947
#
# JRE version: Java(TM) SE Runtime Environment (8.0_73-b02) (build 1.8.0_73-b02)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.73-b02 mixed mode bsd-amd64 compressed oops)
# Problematic frame:
# V [libjvm.dylib+0x3ce9d4] PhaseIdealLoop::idom_no_update(Node*) const+0x12
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

Current thread (0x00007feeef003800): JavaThread "C2 CompilerThread0" daemon [_thread_in_native, id=18947, stack(0x0000700000ec4000,0x0000700000fc4000)]
siginfo: si_signo: 11 (SIGSEGV), si_code: 1 (SEGV_MAPERR), si_addr: 0x0000000000000008
我不知道如何解决这个问题。该程序非常简单，它通过 Kafka 接收消息并根据接收到的消息触发任务。如果我添加两个不同的任务，程序会在 900 - 1,500 条消息后崩溃。所有消息都是相同的，并且程序不使用任何 JNI 东西（据我所知，使用的第 3 方库也不使用任何 JNI）。
我从未遇到过这个问题，但我会 love/need 找到一种方法来找出问题所在。我已经使用了其他版本的 JVM（Java 8.0_66、8.0_73-b02 和 8.0_74-b02）。那我该怎么办？非常感谢！
编辑 (1): 有时我也会得到以下 error/info:
...

编辑 (2)：我将 Java 版本更新为 8.0_74。错误仍然存在:(.

编辑 (3)：核心转储
所以最后我创建了一个核心转储并将其加载到 Java VisualVM（我无法使用 DROY 提供的解决方案，因为调用 jmap 导致另一个错误："Error attaching to core file: Can't attach to the core file"）。使用 VisualVM 创建的线程转储导致：

看起来像 JDK 错误 JDK-6675699。根据错误报告，该错误的修复已反向移植到 8u74、8u81 和 8u82。
请注意（截至目前）最终用户关注 Java Download Site offers 8u73 as the latest version. You can get 8u74 from the Java Developer Download Site。
如果更新到 8u74 不能解决问题，那么您应该将其作为错误报告提交给 Oracle。可能的诊断是您的 运行 代码导致 JIT 代码编译器在尝试编译/优化它时崩溃。这就是 PhaseIdealLoop::idom_no_update 所指示的。
JDK-6675699 针对特定的 JIT 编译器错误。很可能还有其他尚未诊断的 JIT 编译器错误。如果您提交新的错误报告，它可以帮助维护人员追踪这些错误。但是，只有当您可以提供足够的信息让他们重现您的错误时，错误报告才会对他们有用。
（当然，根本原因也可能是完全不同的东西；例如，您的代码中的某些第三方代码破坏了导致编译器崩溃的 JVM 数据结构。但这将是一个巨大的巧合因为腐败会反复破坏编译器……而且只有编译器。）
更新 - 根据这些Release Notes，您实际需要的版本是Java SE 8u74-b32。
我觉得你应该花点时间分析内核。
段错误
这有几个可能的原因。 JVM 本身或包中可能存在错误（其中一些是用 C 或 C++ 编写的）。也可能是由于一起使用了不兼容组件的错误配置。
根据经验，JVM 错误是其中可能性最小的。尽管@Stephen 认为这里很可能是这种情况。
如果您在崩溃时捕获堆栈跟踪，这可能会为您提供一些关于崩溃发生的确切位置的线索。
首先，我看到您需要配置 ulimit -c unlimited 以便您可以将核心文件存储到磁盘。
分析核心文件
完成后，您应该使用以下方法分析核心。
要转换文件，请使用命令行工具 jmap。
jmap -dump:format=b,file=dump.hprof /usr/bin/java core_file
其中：
dump.hprof 是您要创建的 hprof 文件的名称
/usr/bin/java 是生成核心转储
的 java 二进制版本的路径
崩溃报告告诉 JIT 编译器线程中发生了错误：
Current thread (0x00007f89e481c800): JavaThread "C2 CompilerThread1"
按照以下步骤诊断编译器问题：
尝试 JDK9 EA 中可用的最新 JVM 构建：https://jdk9.java.net/download/
如果问题消失，您可以继续使用此版本或尝试找到解决问题的确切提交，然后将其反向移植到 JDK 8. 如何反向移植修复以及如何自己构建 HotSpot - 这是一个单独的话题，但我知道你是否感兴趣。
如果问题仍然存在，请尝试找到有问题的方法并将其排除在编译之外。
Current CompileTask: C2: 114667 5303 4 com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize (157 bytes)
看起来你的情况编译失败 TypeConverterHelper.deserialize()。添加以下 JVM 选项以排除此特定方法：
-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize
如果没有帮助，请尝试通过提供多个 -XX:CompileCommand 来排除更多方法。要查找要排除的候选人，请使用 -XX:+PrintCompilation 并查看打印列表的底部。您还可以从编译中排除整个 类 和包，例如
-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.*::*
尝试一项一项地禁用某些编译器优化。可以尝试的一些选项是：
-XX:-DoEscapeAnalysis
-XX:LoopUnrollLimit=0
-XX:-PartialPeelLoop
-XX:-UseLoopPredicate
-XX:-LoopUnswitching
-XX:-ReassociateInvariants
-XX:MaxInlineLevel=1
-XX:-IncrementalInline
-XX:-RangeCheckElimination
-XX:-EliminateAllocations
-XX:-UseTypeProfile
-XX:AliasLevel=0
是否发现有问题的method/optimization，运行JVM再次用
-XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation
这将在当前目录中创建 hotspot_pid1234.log 文件，其中包含详细的编译日志。
在 bugreport.java.com 提交错误报告。 Select
Product/Category: HotSpot Virtual Machine (errors)
Subcategory: J2SE Server Compiler
确保包括第 5 步中的完整 hs_err_pid.log 和 hotspot_pid.log。如果您能提供一个简化的独立示例来演示问题，那将非常有帮助。
为了获得更快的反应，您还可以 post 向 hotspot-compiler-dev 邮件列表发送消息。
我真的很迷茫，我不知道如何去面对和解决我的问题。我有一段简单的 Java 代码，导致 JVM 崩溃：

我不知道如何解决这个问题。该程序非常简单，它通过 Kafka 接收消息并根据接收到的消息触发任务。如果我添加两个不同的任务，程序会在 900 - 1,500 条消息后崩溃。所有消息都是相同的，并且程序不使用任何 JNI 东西（据我所知，使用的第 3 方库也不使用任何 JNI）。
我从未遇到过这个问题，但我会 love/need 找到一种方法来找出问题所在。我已经使用了其他版本的 JVM（Java 8.0_66、8.0_73-b02 和 8.0_74-b02）。那我该怎么办？非常感谢！

编辑 (3)：核心转储
所以最后我创建了一个核心转储并将其加载到 Java VisualVM（我无法使用 DROY 提供的解决方案，因为调用 jmap 导致另一个错误："Error attaching to core file: Can't attach to the core file"）。使用 VisualVM 创建的线程转储导致：

看起来像 JDK 错误 JDK-6675699。根据错误报告，该错误的修复已反向移植到 8u74、8u81 和 8u82。
请注意（截至目前）最终用户关注 Java Download Site offers 8u73 as the latest version. You can get 8u74 from the Java Developer Download Site。
如果更新到 8u74 不能解决问题，那么您应该将其作为错误报告提交给 Oracle。可能的诊断是您的 运行 代码导致 JIT 代码编译器在尝试编译/优化它时崩溃。这就是 PhaseIdealLoop::idom_no_update 所指示的。
JDK-6675699 针对特定的 JIT 编译器错误。很可能还有其他尚未诊断的 JIT 编译器错误。如果您提交新的错误报告，它可以帮助维护人员追踪这些错误。但是，只有当您可以提供足够的信息让他们重现您的错误时，错误报告才会对他们有用。
（当然，根本原因也可能是完全不同的东西；例如，您的代码中的某些第三方代码破坏了导致编译器崩溃的 JVM 数据结构。但这将是一个巨大的巧合因为腐败会反复破坏编译器……而且只有编译器。）
更新 - 根据这些Release Notes，您实际需要的版本是Java SE 8u74-b32。
我觉得你应该花点时间分析内核。
段错误
这有几个可能的原因。 JVM 本身或包中可能存在错误（其中一些是用 C 或 C++ 编写的）。也可能是由于一起使用了不兼容组件的错误配置。
根据经验，JVM 错误是其中可能性最小的。尽管@Stephen 认为这里很可能是这种情况。
如果您在崩溃时捕获堆栈跟踪，这可能会为您提供一些关于崩溃发生的确切位置的线索。
首先，我看到您需要配置 ulimit -c unlimited 以便您可以将核心文件存储到磁盘。
分析核心文件
完成后，您应该使用以下方法分析核心。
要转换文件，请使用命令行工具 jmap。
jmap -dump:format=b,file=dump.hprof /usr/bin/java core_file
其中：
dump.hprof 是您要创建的 hprof 文件的名称
/usr/bin/java 是生成核心转储
的 java 二进制版本的路径崩溃报告告诉 JIT 编译器线程中发生了错误：
Current thread (0x00007f89e481c800): JavaThread "C2 CompilerThread1"
按照以下步骤诊断编译器问题：
尝试 JDK9 EA 中可用的最新 JVM 构建：https://jdk9.java.net/download/
如果问题消失，您可以继续使用此版本或尝试找到解决问题的确切提交，然后将其反向移植到 JDK 8. 如何反向移植修复以及如何自己构建 HotSpot - 这是一个单独的话题，但我知道你是否感兴趣。
如果问题仍然存在，请尝试找到有问题的方法并将其排除在编译之外。
Current CompileTask: C2: 114667 5303 4 com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize (157 bytes)看起来你的情况编译失败
TypeConverterHelper.deserialize()。添加以下 JVM 选项以排除此特定方法：-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.TypeConverterHelper::deserialize如果没有帮助，请尝试通过提供多个
-XX:CompileCommand来排除更多方法。要查找要排除的候选人，请使用-XX:+PrintCompilation并查看打印列表的底部。您还可以从编译中排除整个 类 和包，例如-XX:CompileCommand=exclude,com.sosse.time.timeseries.gson.*::*尝试一项一项地禁用某些编译器优化。可以尝试的一些选项是：
-XX:-DoEscapeAnalysis -XX:LoopUnrollLimit=0 -XX:-PartialPeelLoop -XX:-UseLoopPredicate -XX:-LoopUnswitching -XX:-ReassociateInvariants -XX:MaxInlineLevel=1 -XX:-IncrementalInline -XX:-RangeCheckElimination -XX:-EliminateAllocations -XX:-UseTypeProfile -XX:AliasLevel=0是否发现有问题的method/optimization，运行JVM再次用
-XX:+UnlockDiagnosticVMOptions -XX:+LogCompilation这将在当前目录中创建
hotspot_pid1234.log文件，其中包含详细的编译日志。在 bugreport.java.com 提交错误报告。 Select
Product/Category: HotSpot Virtual Machine (errors) Subcategory: J2SE Server Compiler确保包括第 5 步中的完整
hs_err_pid.log和hotspot_pid.log。如果您能提供一个简化的独立示例来演示问题，那将非常有帮助。为了获得更快的反应，您还可以 post 向 hotspot-compiler-dev 邮件列表发送消息。
