kettle启动时候报a fatal exception has occurred

本人刚接触ETL工具 Data Integration - Kettle ，下载了kettle6.0版本，但是在window +jdk1.7(32位)下启动报错，

使用SpoonDebug.bat写的日志信息是：

DEBUG: Using JAVA_HOME
DEBUG: _PENTAHO_JAVA_HOME=D:\software\Java\jdk1.7.0_79
DEBUG: _PENTAHO_JAVA=D:\software\Java\jdk1.7.0_79\bin\java.exe

D:\software\kettle\data-integration>"D:\software\Java\jdk1.7.0_79\bin\java.exe"  "-Xms1024m" "-Xmx1500m" "-XX:MaxPermSize=256m" "-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2" "-Djava.library.path=libswt\win32" "-DKETTLE_HOME=D:\software\kettle\data-integration" "-DKETTLE_REPOSITORY=" "-DKETTLE_USER=" "-DKETTLE_PASSWORD=" "-DKETTLE_PLUGIN_PACKAGES=" "-DKETTLE_LOG_SIZE_LIMIT=" "-DKETTLE_JNDI_ROOT=" -jar launcher\pentaho-application-launcher-6.0.0.0-353.jar -lib ..\libswt\win32  /level:Debug
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

经高人指点，将Spoon.bat中

if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx2048m" "-XX:MaxPermSize=256m" 修改的小一些就可以启动了。

具体原因可能是32位的JDK可使用的最大内存的限制。kettle官网http://wiki.pentaho.com/display/EAI/A+guide+to+setting+up+PDI+in+a+Microsoft+client-server+style+environment  提示信息（the limit for 32-bit JVM is around 1583)
