Are there a way to attach to the env pointer a native object? Let me
be more clear.

I have the following native function (simplified):

solve(JNIEnv * env , jobject obj1 , void* alpha){
...
nativeobject *native1 = new nativeobject;

}

and I wan to acces the j1 object form another native function

setup (JNIEnv * env){
...
}
If I have only the C part, I would cast the "native1" object, pass to
"setup" and cast back the object, but since the setup function is
called from java, I don't know how to access native1 object from
"setup". Is it possible?
