|
|
* DESCRIPTION
|
|
* This test exercises the JVMTI event NativeMethodBind.
|
|
* It verifies that the event will be properly sent:
|
|
* - for the native method called for the first time
|
|
* - when the JNI RegisterNatives() is called.
|
|
* The test works as follows. The java part invokes the native method
|
|
* 'nativeMethod()' twice. At the first time that method registers
|
|
* another native method 'anotherNativeMethod()' for the dummy class
|
|
* 'TestedClass'. Registration is made through the JNI RegisterNatives()
|
|
* call. Being invoked at the second time, the nativeMethod() just returns.
|
|
* In accordance with the spec, it is expected that the NativeMethodBind
|
|
* will be generated only one time for the nativeMethod(), and only one
|
|
* time for the anotherNativeMethod().
|
|
* COMMENTS
|
|
* The test has been fixed due to the bug 4967116.
|
|
* Fixed the 4995867 bug.
