我看你里面说的，可以这样归纳，你用sun的JDK1.5是可以的，ibm jvm1.4.2就不可以
其实这里不只是厂家的差别，最大的差别还有版本的差别，sun JDK1.4.2就有很多不同的版本的下面是myeclipse的安装文档里的
Requirements
Below is a list of software you will need to install in order to get MyEclipse working:JDK 1.4+ (Sun or IBM) or JDK 1.5
http://java.sun.com/j2se/downloads/index.html
Eclipse 3.1 SDK
http://www.eclipse.org/downloads/index.php
MyEclipse 4.0
http://www.myeclipseide.com/ContentExpress-display-ceid-10.html
(OPTIONAL) WinZip 9.0
http://www.winzip.com/downwz.htm
You are free to use any archiving software, this guide happens to use WinZip 9.0
As noted in the Preface, these requirements are the most recent supported release of these pieces of software, if you are reading this document at a later date and JDK 1.6, Eclipse 3.2 and MyEclipse 4.0.1 are all available, you can verify that this is supported very quickly by checking the release notes on the MyEclipse site or asking in the forums我想按照这个，应该是可以的因为我这里原来是sun1.4.2_06也是可以的
