> After intrumenting the public api classes,  DRLVM failed to load "com.vladium.emma.rt.RT" 
> The ibm j9 works fine with both situation.
> 1. Using normal emma.jar and the instrumented classes in your bootclasspath.
> It will fail for: 
> java/lang/ExceptionInInitializerError : (null)
> HMYEXEL062E 内部 VM 错误：未能创建 Java VM
> FAILED to invoke JVM.
> 2. Using customized emma.jar [1] and the instrumented classes in your bootclasspath.
> It will fail for :
> java/lang/ClassFormatError : com/vladium/emma/rt/RT : invalid magic
> HMYEXEL062E 内部 VM 错误：未能创建 Java VM
> FAILED to invoke JVM.
> (the magic of com.vladium.emma.rt.RT is corrent, the fail message should be reported by mistake)
