问题:
Unable to create the selected preference page.
com/genuitec/eclipse/core/ui/preference/MyEclipsePreferencePage (Unsupported major.minor version 49.0)

解决办法:
方式一:
系统级别path高于用户级别path jdk路径一定在系统path比较保险

方式二:
myeclipse的快捷方式
添加:-vm D:/Program Files/Java/jdk1.5.0_11/bin/javaw.exe 指定到你的jdk
"D:/Program Files/Java/eclipse/eclipse-SDK-3.3-win32/eclipse/eclipse.exe"
-vm D:/Program Files/Java/jdk1.5.0_11/bin/javaw.exe
-product com.genuitec.myeclipse.product.ide

方式三:
修改eclipse(注不是myeclipse下的eclipse目录)中的eclipse.ini文件:
路径如:
D:/Program Files/Java/eclipse/eclipse-SDK-3.3-win32/eclipse
操作:添加-vm D:/Program Files/Java/jdk1.5.0_11/bin/javaw.exe
结果如:
-showsplash
com.genuitec.myeclipse.product
--launcher.XXMaxPermSize
256m
-vmargs
-Xms128m
-Xmx512m
-Dosgi.splashLocation=d:/Program Files/java/MyEclipse 6.0/eclipse/MyEclipseSplash.bmp
-Duser.language=en
-XX:PermSize=128M
-XX:MaxPermSize=256M
-vm D:/Program Files/Java/jdk1.5.0_11/bin/javaw.exe
