Patch: FYI: fix type of jni_env

[Tom Tromey]

I'm checking this in.

There was no reason for natThread::jni_env to be declared as void*.
I fixed this and removed a couple casts as a result.

from  Tom Tromey  <tromey@redhat.com>

	* java/lang/natThread.cc (finalize_native): Remove cast.
	(_Jv_GetCurrentJNIEnv): Likewise.
	* include/jvm.h (struct natThread) <jni_env>: Declare as
	_Jv_JNIEnv*.
