the Enum type can't be decomplier completely

[tiann]

I open a enum type in a class file , ionly to find that the enum lose some infomation,e.g.
public enum BizFunNo{
F_INIT(100,'init register'),F_NORMAL(101,'nolamai trans');
punlic void setXXX
public void getXXX
....
}
when i open the enum with this plugin,i found it be this:
public enum BizFunNo{
F_INIT,F_NORMAL;
punlic void setXXX
public void getXXX
....
}
why?
