java程序内存不下降,但是也没有内存泄露怎么分析?_course

我们用java开发的程序.运行过程中使用任务管理器观察内存可以达到700M.使用java自带的jvisualvm.exe查看内存申请了200多用了100M,请问剩下的500M去哪里了.用什么方法可以找到这些内存的去向.

动态分析java代码结构_course

首先非常感谢您来到这里， 我最近需要实现一个功能模块，这个模块的功能和ecplise的大纲视图类似。 用户在JTextArea中连续编码，程序需要动态分析用户当前正在编辑的类，通过一个树形结构来显示这个类的结构。 这个树形结构以类名为根，根下节点为类属性和方法，甚至内部类，当用户键入一个新的成员时，就在树中插入一个相应的节点。 我只是一个大三学生，这个任务对我来说实在有点困难，所以希望得到您的指点或者创意。 我接收到的想法有： 1、通过JDK中提供的API实现一个代码的词法分析器和语法语义分析器； 2、获取JDK中javac的源码，阅读重用这些源码 3、动态编译源码，对字节码进行解析 以上这些想法只有第3个我有办法实现，但仍然太复杂，所以想听听您的建议，仅此而已，非常感谢！

Java数组的内存分配和逃逸分析的问题_course

刚看了一篇关于逃逸分析的博客说：Java数组长度小于等于64会是在栈分配的，大于64的会分配在堆里面。 问题1：这个是真的吗？官方文档哪里有些？ 问题2：如果是真的，那么基础数据类型数组和对象数组都一样在小于64在栈里面分配吗？ 问题3：把对象的内存分配到栈的前提是什么？不会逃逸就可以了吗？ 问题4：Java的栈上分配都是都是JVM自动优化，不能指定分配在堆还是栈上面吗？

Java内存分析，加载类中包含其他类的加载顺序_course

已知一个Person类，包含的属性home属于Home类 public class Person { String name; int age; String[] hobby; Home home; 省略get、set方法等。。。 } public class Demo { public static void main(String[] args) { Person p = new Person(); p.setAge(18); p.setName("小鱼"); Home h = new Home(); h.setAddress("长春"); h.setArea(100); h.setRoomNum(3); p.setHome(h); } } 在执行main方法时（前台Person类和Home类之前都没有加载过），遇到Person p = new Person();加载Person类，加载Person类的时候会同时加载Home类吗，还是只有等到执行到Home h = new Home();才会加载Home类。。

Java 内存泄漏问题_course

因为系统有内存泄露问题，导致频繁的Full GC，用jmap将内存使用情况dump下来，然后通过mat分析了一下，发现是由于缓存map和更新该map的线程池导致的，截图见附件，下面这个是涉及到的类，研究了好几天这个问题，现在终于定位到具体的代码，耐于经验有限，想请教一下大家都是怎么处理系统中缓存数据的，有闲暇时间的帮看下下面的代码应该如何修改。。 还有个问题就是，定时更新run()里的程序总是不会立即执行，scheduleAtFixedRate的第二个参数设为0也不管用，只有这次执行完，下次再走这儿时cacheMap里才有上次的数据。所以只好在外面再执行一遍，总觉得这么写很奇怪 [code="java"] public class CachedDataManager extends DataManagerDecorator { private static ScheduledExecutorService pool; private long timeLimited;//缓存中数据更新间隔时间 60s private int poolSize;//线程池大小,20 private static int cacheSize; public static Map cacheMap;// = new HashMap(); public Object getResult(final String methodName, final Map parameterMap) { if (cacheMap == null) { synchronized (CachedDataManager.class) { if (cacheMap == null) { cacheMap = new ConcurrentLinkedHashMap.Builder() .maximumWeightedCapacity(cacheSize).build(); } } } // 根据HashCode生成缓存map的key final String mapKey = new KeyCreater(methodName, parameterMap) .getHashCode(); // 缓存中没有该条数据则放入有定时更新策略的线程池 if (!cacheMap.containsKey(mapKey)) { if (pool == null) { pool = Executors.newScheduledThreadPool(poolSize); } pool.scheduleAtFixedRate(new Runnable() { @Override public void run() { Object obj = dataManager.getResult(methodName, parameterMap); cacheMap.put(mapKey, obj); } }, 0, timeLimited, TimeUnit.SECONDS); } else if (cacheMap.get(mapKey) != null) { return cacheMap.get(mapKey); } //因为上面的不会立即执行，所以第一次查询执行这里 Object obj = dataManager.getResult(methodName, parameterMap); cacheMap.put(mapKey, obj); return cacheMap.get(mapKey); } } [/code]

java.lang.Class内存泄露_course

一个基于eclipse的工具软件，将eclipse从3.5升级到3.7之后发现内存泄露严重，通过MAT（Eclipse Memory Analyzer）分析内存发现，泄露最严重的竟然是java.lang.Class，前后两次的数据如下： Number of Objects Used Heap Size Retained Heap Size Retained Heap, % 12,687 93,848 **98,413,488** 15.02% 12,710 94,424 **166,305,000** 20.14% 这个数据很奇怪，Class的实例个数基本没变，但是引用内存却增加了将近70M，不知道什么原因，请教各位高手指点一二！

java 程序内存占用的问题_course

最近在维护一个java 程序 有关内存占用的问题，请各位大神科普。 在本地 windows 上 启动tomcat 占用内存 几十 M 期间处理的任务 1.程序向另一个服务器建立 客户端连接 200多条 （netty） 并保持长连 每过80秒发送心跳。可用内存在每一次心跳都会有一定的下降并且没有回升 2.有个Thread 会每过10秒到数据库（mysql）获取记录 ，创建五条Thread（最大5条）对记录获取相关的连接（以上200多条连接中获取）进行处理，可用内存也会下降 在已用内存到达一定高度，可用内存便会回升，这是在windows 测试的结果，内存使用情况我觉得很健康 放在linux 服务器上 tomcat 启动内存就占用了200M多，每次心跳和处理记录也在增加，但内存达到一定高度 可用内存并没有回升，tomcat直接内存溢出了（生产环境） 我把测试环境的监控贴出来唉大家帮帮忙分析一下  

IBM JDK1.4.2 javacore分析原因_course

请牛人帮忙分析一下这个javacore文件，基本问题已经定位在Thread-1上，从stack看，是at java.lang.Class.forName1调用的时候出错了，clSearchForNameCache。再具体的信息就不太清楚，大家帮着瞧瞧，出个主意。 另外这个javacore不是OOM引起的，是signal 11 received。 [b]问题补充：[/b] 谢谢RednaxelaFX的回复，从stacktrace来看，应该是Shutdown运行的时候调用了class.forname方法，实在是不知道是哪里引起来的错误。我贴一下ibm jdk的源码，当然只是包括stack里面涉及的那两个类。还望大家多多指教。 [b]问题补充：[/b] 这个错误不是每次都产生，具有一定随机性，但是出错时都是同一个原因导致的。上传一下出错时产生的core dump文件，希望能有帮助。该如何分析这个dump以获得更多的信息呢？gdb？ [b]问题补充：[/b] 重要发现 （gdb coredump后的结果）： Core was generated by `/usr/local/java14/bin/java -classpath /home/mdebt/app/dist-NO_JRE//config:/home'.

在docker里运行的java程序如何避免内存超过容器限制导致的os kill？_course

条件 1. docker里运行java程序，docker容器限制了内存 1. jvm的heap内存必须常驻物理内存，不能被置换 1. jvm的native、direct内存不可控，也没办法限制上限 目标：如何保证运行java程序的docker容器不会因为内存超过限制而被os kill 我的想法： 1. jvm是否有参数可以让native、direct内存通过文件映射分配，通过映射文件去和容器剩余物理内存进行置换 2. docker容器打开swap开关，但如何保证jvm的heap常驻物理内存 跪求大佬带一把，感激不尽
