Do I need to delete JavaVM or JNIEnv pointers?

Question

In JNI do I need to either delete the pointers or call DeleteGlobalRef for them?
JavaVM* theVM;
jint JNI_Onload(JavaVM *vm, void *reserved)
      theVM = vm;
      return JNI_VERSION_1_4;
//When done in native function, should I do either:
      //delete theVM;
      //delete env;
//or this:
      //env->DeleteGlobalRef( theVM );

Answer 1

The Sun VM will not exit a process space once started.
So cleaning up the resources associated to the VM instance itself is pointless.
And it might cause the application to fail.
