Java 运行时环境检测到致命错误：SIGSEGV (0xb) at pc=0x00007f3457bc96ae, pid=1192, tid=0x00007f345e1ff700

Question

我正在使用两个公司的手指 sdk。该项目在 java ee 中运行。执行程序时出现以下错误。崩溃并不总是发生。

我有这个作为开始：

 #
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f3457bc96ae, pid=1192, tid=0x00007f345e1ff700

# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.121-b13 mixed mode linux-amd64 compressed oops)
# Problematic frame:

#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

有问题的框架如下：

我无法理解崩溃日志 .The crash log is given here 。你能帮我理解崩溃报告吗？我该如何解决这个问题？

Answer 1

这是 SecuGen.FDxSDKPro.jni.JSGFPLib.MatchTemplate 实现的错误。正如它的包名所说，它是 JNI，它可以使 JVM 崩溃。您应该联系实施者。

Answer 2

崩溃发生在“libsgfpamx.so”文件中，您可以看到有问题的框架指示崩溃位置。

# Problematic frame:
# C  [libsgfpamx.so+0xb6ae]  _DecodeANSITemplate+0x2e

You need to examine below calls
j  SecuGen.FDxSDKPro.jni.JSGFPLib.MatchTemplate([B[BJ[Z)J+0
j  enroll.verify.FingerMatching.fingerprintVerify(LSecuGen/FDxSDKPro/jni/JSGFPLib;[B[B)Z+20
j  enroll.verify.FingerMatching.fingerPrintIndetify([B[[B)Z+64
j  era.data.FingerPrintVerification.fingerVerfyFromTemplate(Lera/data/LoginModel;)Ljava/util/List;+394
j  finger.servlet.FingerVerification.doPost(Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V+744

在调用 libsgfpamx.so 之前检查您传递的参数，这可能会给您一些线索。
