For the first time I am using Libgdx. I can download and unzip finished. But error occured Unable to start daemon process Error occurred during initialization of VM Could not reserve enough space for 1536000KB object heap In Android studio I got same problem. But I can Change it by gradle.properties----> org.gradle.jvmargs=-Xmx512m Then it works fine. But in libgdx, I don't
我第一次使用Libgdx。 我可以下载并解压缩完成。 但错误发生 无法启动守护进程 VM初始化期间发生错误无法为1536000KB对象堆预留足够的空间 在Android studio中，我遇到了同样的问题。 但我可以改变它 gradle.properties ----> org.gradle.jvmargs = -Xmx512m 然后它工作正常。 但在libgdx中，我不知道 在您的系统的环境变量中设置一个系统变量。 Variable name: _JAVA_OPTIONS Variable value: -Xmx512M
Is there a utility (for Windows) that uses up memory so I can create a JVM "could not reserve enough space for object heap" error? I want to use up this memory in a process outside of the JVM. Just use the -Xms flag java -Xms3g org.foo.Main The above will try to create an initial heap size of 3 GB, just adjust the number so it is larger than the total memory of your system (physic
是否有一个实用程序（对于Windows）耗尽内存，因此我可以创建一个JVM“无法为对象堆预留足够的空间”错误？ 我想在JVM之外的一个进程中使用这个内存。 只需使用-Xms标志 java -Xms3g org.foo.Main 以上将尝试创建一个3 GB的初始堆大小，只需调整该数字，使其大于系统的总内存（物理和虚拟） 我想你可以试试这个： String s = "b"; for (int i = 0; i < 1000 000; i++) { s+="b"; } 因为每次运行s + =“b”行时都会分
Just faced with strange issue. When i type java -version i got Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. . java -Xms64m -Xmx64m -version This command works fine java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode) If i
刚刚面临奇怪的问题。 当我输入 java -version 我有 Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. 。 java -Xms64m -Xmx64m -version 这个命令工作正常 java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode) 如果我将xms，xmx更改为12
I am getting this error in a program that creates several (hundreds of thousands) HashMap objects with a few (15-20) text entries each. These Strings have all to be collected (without breaking up into smaller amounts) before being submitted to a database. According to Sun, the error happens "if too much time is being spent in garbage collection: if more than 98% of the total time is spent
我在一个程序中得到这个错误，该程序创建了几个（数十万个）HashMap对象，每个对象都有几个（15-20）个文本项。 这些字符串在提交到数据库之前都已收集（没有分解成更小的数量）。 据Sun称，错误发生在“如果在垃圾收集中花费了太多时间：如果超过总时间的98％用于垃圾收集，并且小于2％的堆被恢复，则会抛出OutOfMemoryError。 ”。 显然，可以使用命令行将参数传递给JVM 通过“-Xmx1024m”（或更多）或者增加堆大小 完全
I'm trying to use JUnit in a makefile but I can't get it to work. My folder structure is as follows (makefile is in myProject): myProject |--bin |--main |--org |--myPackage |--test |--org | |--myPackage | |--lib where /main contains main files, /test contains test files and /lib contains hamcrest-core-1.3.jar and junit-4.12.jar My makefile is as follows
我试图在makefile中使用JUnit，但我无法使它工作。 我的文件夹结构如下（makefile在myProject中）： myProject |--bin |--main |--org |--myPackage |--test |--org | |--myPackage | |--lib 其中/ main包含主文件，/ test包含测试文件，/ lib包含hamcrest-core-1.3.jar和junit-4.12.jar 我的makefile如下所示： JAVAC = javac JVM = java JAVADOC = javadoc MKBIN = mkdir -p bin JAVAC_F

我有这个要求 - 输入字符串，如下面所示 8This8 is &reallly& a #test# of %repl%acing% %mul%tiple 9matched9 9pairs 我想去掉匹配的单词边界（匹配对是8或者或者％等），并且会导致以下结果 This is really a test of repl%acing %mul%tiple matched 9pairs 用于这些对的字符列表可以有不同，例如8,9，％，＃等，并且只有与每种类型的开始和结束匹配的字将被剥离那些字符，并且嵌入字中的相同字符保留在其中它是。
In the spirit of question Java: Why does MaxPermSize exist?, I'd like to ask why the Sun JVM uses a fixed upper limit for the size of its memory allocation pool. The default is 1/4 of your physical RAM (with upper & lower limit); as a consequence, if you have a memory-hungry application you have to manually change the limit (parameter -Xmx), or your app will perform poorly, possible ev
本着质疑Java的精神：为什么MaxPermSize存在？，我想问一问，为什么Sun JVM对内存分配池的大小使用固定的上限。 默认值是物理RAM的1/4（带有上限和下限）; 因此，如果您有一个需要内存的应用程序，您必须手动更改限制（参数-Xmx），否则您的应用程序将执行得很差，甚至可能会因OutOfMemoryError而崩溃。 为什么这个固定限制甚至存在？ 为什么JVM不按需要分配内存，就像本机程序在大多数操作系统上一样？ 这将解决Java软
I'm running Jenkins 1.557. I have a job that I need to be built with a 32-bit version of JDK 1.6_u45. I have that version properly configured in my job's JDK setting. However, when I attempt to run the job, I get the following error. Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. If I switch the job
我正在运行詹金斯1.557。 我有一份工作需要使用32位版本的JDK 1.6_u45构建。 我在作业的JDK设置中正确配置了该版本。 但是，当我尝试运行该作业时，出现以下错误。 Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. 如果我将作业的JDK设置切换为64位版本，则可以创建JVM并且它可以正常运行。 服务器有8GB可用内存，我甚至试图传入
I'm writing a wrapper to Lucene. When a search request is made frequently, it's possible "Could not reserve enough space for object heap" will be thrown. How can I get the size of the object heap? And how can I solve that? I believe that the underlying problem is the same as is described in the good answers to the SO question Could not reserve enough space for object heap.
我正在写一个Lucene的包装器。 当频繁发出搜索请求时，可能会出现“无法为对象堆预留足够的空间”。 我如何获得对象堆的大小？ 我该如何解决这个问题？ 我相信底层问题与SO问题的良好答案中描述的相同无法为对象堆预留足够的空间。 也就是说，JVM试图向OS询问堆的内存，而操作系统拒绝，因为它已经将所有虚拟内存分配给其他进程。 我期望在频繁启动索引器时发生这种情况，因为： 它正在增加系统的平均负载（运行/等待
