centos7系统 gdb调试jdk11源码

centos7 gdb调试jdk11源码

##首先你得编译一个debug版本的jdk11。教程centos7下openjdk11源码下载编译安装_openjdk11下载-CSDN博客

##gdb 启动java进程 设置运行参数、设置断点

运行、调试进入main断点

gdb /home/yym/code/jdk11u-master/build/linux-x86_64-normal-server-slowdebug/jdk/bin/java

(gdb) set args GDBDebugJava

(gdb) b b JavaMain

(gdb) b InitializeJVM

(gdb) b JNI_CreateJavaVM_inner

(gdb) handle SIGSEGV pass noprint nostop

##GDBDebugJava.java代码

import java.util.concurrent.TimeUnit;

public class GDBDebugJava {

    public static void main(String[] args) {
        int i=0;
        try {
            TimeUnit.SECONDS.sleep(1);
            System.out.println("mi"+i++);
        }catch (Exception e) {
            e.printStackTrace();
        }
        MiDept miDept = new MiDept();
        miDept.show();
    }

}

##MiDept.java

public class MiDept {

    public void show() {
        System.out.println("mi--------------");
    }

}
