Specifying the Java virtual machine
Here is a typical Eclipse command line: eclipse -vm c:\jdk1.4.2\jre\bin\javaw Tip: It's generally a good idea to explicitly specify which Java VM to use when running Eclipse. This is achieved with the "-vm" command line argument as illustrated above. If you don't use "-vm", Eclipse will look on the O/S path. When you install other Java-based products, they may change your path and could result in a different Java VM being used when you next launch Eclipse. To create a Windows shortcut to an installed Eclipse: Navigate to eclipse.exe in Windows Explorer and use Create Shortcut on the content menu.
Select the shortcut and edit its Properties. In the Target: field append the command line arguments.
Opening this shortcut launches Eclipse. (You can drag the shortcut to the Windows Desktop if you want to keep it in easy reach.)
意思是指定自己的jvm，按照上面，在eclipse.ini的开头加上：
-vm
$JAVA_HOME\bin\javaw.exe // win下是"\"
或者将
--launcher.XXMaxPermSize
256M --launcher.XXMaxPermSize
256m // 改为 --launcher.XXMaxPermSize
128M --launcher.XXMaxPermSize
128m
