MethodEntryEvent.location() is not returning null for native method,
 but the Method.location() returns null.

 the location() method in these interfaces(MethodEntryEvent&Method)
 are from Locatable, which is supposed to return null location
 for a nativeMethod.

3)Start the targetVM with the command
java -Xdebug -Xnoagent
-Xrunjdwp:transport="dt_socket",server=y,suspend=y,address=5670
HelloWorld
4)Start the debugger with the command
java StackFrameTest


Attachments: in evaluate.jar
 --------------------------
 1. JDIScaffold.java
 2. VMConnection.java
 3. StackFrameTest.java
 4. HelloWorld.java
 5. HelloWorldImp.c(used VC++5,to generate library file)
