|
* DESCRIPTION
|
|
* This test exercises the JVMTI event NativeMethodBind.
|
|
* It verifies that binding native method can be redirected during
|
|
* the event callback.
|
|
* The test works as follows. An agent part enables the NativeMethodBind
|
|
* generation. Then the java part invokes the native method 'nativeMethod()'
|
|
* which leads to the NativeMethodBind generation. In NativeMethodBind
|
|
* callback incoming address of the nativeMethod() is changed to the
|
|
* address of another native method 'redirNativeMethod()'. Both functions
|
|
* nativeMethod() and redirNativeMethod() count their calls.
|
|
* In accordance with the spec, the nativeMethod() should not be invoked
|
|
* and the redirNativeMethod() should be invoked once.
|
|
* COMMENTS
|
|
* The test has been fixed due to the bug 4967116.
|
|
* Fixed the 4995867 bug.
