Hi friends 
I have a problem while running a java code with GCJ...
i recently cross compiled GCC for arm with added language option as java. so
i got arm-unknown-linux-gnu-gcj..
My java code is 

class helloworld
{
    static public void main(String argc[])
   {
         System.out.println("Hello World !");
   }
}

so i am crosscompiling my java code like this...
arm-unknown-linux-gnu-gcj -g --main=helloworld -o helloworld helloworld.java
and running like this
./helloworld 
the above should print Hello World ! as far as my understanding since GCJ
does not require JVM
while compiling and running it is not giving any error or warning.. 
but to some extent GDB helped me to atleast post here.. 
this is my GDB dump..
