/**
|
|
* The test checks that invocation with all threads resumption
|
|
* and the single threaded one will be performed properly through
|
|
* the JDI method<br>
|
|
* <code>com.sun.jdi.ObjectReference.invokeMethod()</code>.
|
|
* The following assertions are verified:
|
|
* <li>by default, all threads in the target VM are resumed while
|
|
* the method is being invoked
|
|
* <li>when the invocation completes, all threads in the target VM
|
|
* are suspended, regardless their state before the invocation
|
|
* <li>only the specified thread will be resumed with the
|
|
* <i>INVOKE_SINGLE_THREADED</i>
|
|
* <li>upon completion of a single threaded invoke, the invoking
|
|
* thread will be suspended once again.<br>
|
|
*
|
|
* A debuggee part of the test starts several threads. Then debugger
|
|
* calls the JDI method without and with the flag
|
|
* <i>ObjectReference.INVOKE_SINGLE_THREADED</i> sequentially. During
|
|
* the invocations and after them the threads state is expected to be as
|
|
* described above.
