[LLVMdev] Using StartJnjvmWithJIT from jnjvm.cpp in VMKit

[Sri]

Hi Gael
           Thank you for your clarification. I have generated .bc from 
vmjc by giving java byte code ,  now generated .bc having 
StartJnjvmWithoutJIT function. So , I write a simple application as you 
mentioned and passed the mainclass as "HelloWorld" and argv is nothing 
since my java program not taking any arguments. I am getting following error
*j3: JavaRuntimeJIT.cpp:381: void *j3ResolveVirtualStub(j3::JavaObject 
*): Assertion `FI->Metadata != __null && "Wrong stack trace"' failed.**
**Aborted (core dumped)*
Am I missing anything here.

Thanks

Regards
Sri.
