|
* DESCRIPTION
|
|
* The test exercises that the JVMTI function RedefineClasses()
|
|
* enable to redefine a local inner class properly.
|
|
* Redefiniton is performed in asynchronous manner from a separate
|
|
* thread when the VM is provoked to switch into compiled mode.
|
|
* The test works as follows. Two threads are started. One is a java
|
|
* thread creating and executing a local class in an instance
|
|
* invoker method of the outer class. Second is a native thread
|
|
* executing an agent code. Then the local class method
|
|
* 'redefclass030HotMethod()' is provoked to be compiled (optimized),
|
|
* and thus the JVMTI event 'CompiledMethodLoad' should be sent. After
|
|
* that, the agent redefines the local class.
|
|
* Different kinds of outer fields and a local variable of the outer
|
|
* invoker method are accessed from executing methods in both versions
|
|
* of the local class. Upon the redefinition, the main test thread verifies
|
|
* via the outer fields/local variable values that the inner methods
|
|
* have been redefined. It also verifies that the outer class
|
|
* is still can access the local class fields after the redefinition.
