Eclipse条件断点不起作用 [英] Eclipse conditional breakpoint doesn't work

问题描述

我遇到的问题是条件断点在我的电脑上不起作用。我使用以下代码：

I faced with issue that conditional break point doesn't work on my PC. I use following code:

package test;

public class Main {

    public static class C1 {
        public static C1 c = new C1();

        public Boolean b = null;

        private boolean isB() {
            if (b == null) {
                b = Boolean.TRUE;
            }
            return b; //USE BREAKPOINT HERE
        }
    }

    public static void main(String[] args) throws Exception {
        Thread[] threads = new Thread[100];
        for (int i = 0; i < 100; i++) {
            Thread t = new Thread(new Runnable() {
                public void run() {
                    C1.c.isB();
                }
            });
            threads[i] = t;
        }
        for (Thread t : threads) {
           t.start();
        }
   }
}

条件断点设置为返回b;行并使用Boolean.TRUE.equals（b）条件。
我在没有任何插件的情况下重新安装Eclipse并尝试了不同版本的Java 8，但每次我得到相同的错误时，都会说条件断点遇到运行时异常。原因：java.lang.InternalError：获取了ReferenceType的MethodID即不是ReferenceType的成员发现检索堆栈帧。

The conditional breakpoint is set to "return b;" line and use "Boolean.TRUE.equals(b)" conditional. I reinstall Eclipse without any plugin and tried different versions of Java 8, but each time I get the same error, that says "Conditional breakpoint encountered runtime exception. Reason: java.lang.InternalError: Got MethodID of ReferenceType that is not a member of the ReferenceType occured retrieving stack frames."

我不使用任何JRebel，DCEVM或一些分析工具。

I don't use any JRebel, DCEVM or some profiling tools.

可能是什么原因？它可能是CPU相关问题吗？我使用的是英特尔6700K。 Windows 10 + JDK8u111 + Neon.1a版本（4.6.1）。也不适用于Eclipse Mars。

What can be the reason? Could it be CPU related issue? I use Intel 6700K. Windows 10 + JDK8u111 + Neon.1a Release (4.6.1). Also doesn't work with Eclipse Mars.

推荐答案

我在Eclipse Photon 2018上使用JDK 8和7（均为64位）进行了测试

I've tested this with JDK 8 and 7 (both 64 bit) on Eclipse Photon 2018

版本：Photon Release（4.8 .0）
构建ID：20180619-1200

Version: Photon Release (4.8.0) Build id: 20180619-1200

并且断点工作正常。

我怀疑这取决于您的JDK或Eclipse版本。

I suspect this is down to your JDK or Eclipse version.
