failed to create the java virtual machine

eclipse启动时报错为failed to create the java virtual machine，是因为修改了内存，结果就给报错了，

修改后为-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20140116-2212

-product

org.eclipse.epp.package.jee.product

--launcher.defaultAction

openFile

--launcher.XXMaxPermSize

256M

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

640m

--launcher.defaultAction

openFile

--launcher.appendVmargs

-vmargs

-Dosgi.requiredJavaVersion=1.6

-Xms256m

-Xmx640m

然后重新启动，报错，然后就又改为

-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20140116-2212

-product

org.eclipse.epp.package.jee.product

--launcher.defaultAction

openFile

--launcher.XXMaxPermSize

256M

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

--launcher.defaultAction

openFile

--launcher.appendVmargs

-vmargs

-Dosgi.requiredJavaVersion=1.6

-Xms256m

-Xmx640m

再重启就可以了。
