eclipse failed to create the java virtual machine
解决方法:
1.问题现象
2.java虚拟机初始化失败!寻找eclipse解压路径
3.寻找eclipse初始化文件
4.右击打开(此处以ultraedit打开为例)
5.打开寻找初始化。虚拟机为java永久生成对象(Permanate generation)如,class对象、方法对象这些可反射(reflective)对象分配内存限制设置(原256,设置为128)
注意:此处设置不可太小,且有两处,图中已有标注
6.保存重启eclipse
说明:PermSize和MaxPermSize指明虚拟机为java永久生成对象(Permanate generation)等这些可反射(reflective)对象分配内存限制,这些内存不包括在Heap(堆内存)区之中。
-Xms128m
表示JVM Heap(堆内存)最小尺寸128MB,初始分配
-Xmx512m
表示JVM Heap(堆内存)最大允许的尺寸256MB,按需分配。
-XX:PermSize=64MB 最小尺寸,初始分配
-XX:MaxPermSize=256MB 最大允许分配尺寸,按需分配
过小会导致:java.lang.OutOfMemoryError: PermGen space
