最近在开发的android项目中安装了一个插件JD-Eclipse，用于反编译android项目，安装成功后，重启eclipse，打开主界面，过几秒后eclipse自动关闭。再重启，还是这样。
查看错误日志，显示如下：
!ENTRY org.eclipse.osgi 2 0 2011-02-27 13:44:07.375

找原因找了半天，原来纯碎是虚拟内存不足。修改eclipse的eclipse.init配置文件，增大虚拟内存。配置文件内容如下：
-startupplugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar--launcher.libraryplugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503-productorg.eclipse.epp.package.jee.product--launcher.defaultActionopenFile--launcher.XXMaxPermSize512M-showsplashorg.eclipse.platform--launcher.XXMaxPermSize512m--launcher.defaultActionopenFile-vmargs-Dosgi.requiredJavaVersion=1.5-Xms80m-Xmx512m
这下好了，再也不自动关闭了。
