/**
|
|
* The test for the implementation of an object of the type <BR>
|
|
* EventSet. <BR>
|
|
* <BR>
|
|
* The test checks that results of the method <BR>
|
|
* <code>com.sun.jdi.EventSet.suspendPolicy()</code> <BR>
|
|
* complies with its spec. <BR>
|
|
* <BR>
|
|
* The test checks that for a VMDeathEvent set, <BR>
|
|
* the method returns values corresponding to one <BR>
|
|
* which suspends the most threads. <BR>
|
|
* The cases to check include event set containing two more <BR>
|
|
* VMDeathRequests with suspendPolicies <BR>
|
|
* SUSPEND_ALL and SUSPEND_NONE. <BR>
|
|
* <BR>
|
|
* The test has three phases and works as follows. <BR>
|
|
* <BR>
|
|
* In first phase, <BR>
|
|
* upon launching debuggee's VM which will be suspended, <BR>
|
|
* a debugger waits for the VMStartEvent within a predefined <BR>
|
|
* time interval. If no the VMStartEvent received, the test is FAILED. <BR>
|
|
* Upon getting the VMStartEvent, it makes the request for debuggee's <BR>
|
|
* ClassPrepareEvent with SUSPEND_EVENT_THREAD, resumes the VM, <BR>
|
|
* and waits for the event within the predefined time interval. <BR>
|
|
* If no the ClassPrepareEvent received, the test is FAILED. <BR>
|
|
* Upon getting the ClassPrepareEvent, <BR>
|
|
* the debugger sets up the breakpoint with SUSPEND_EVENT_THREAD <BR>
|
|
* within debuggee's special methodForCommunication(). <BR>
|
|
* <BR>
|
|
* In second phase to check the above, <BR>
|
|
* the debugger and the debuggee perform the following loop. <BR>
|
|
* - The debugger sets up VMDeathRequests, resumes <BR>
|
|
* the debuggee, and waits for the VMDeathEvent. <BR>
|
|
* - The debuggee ends to be resulting in the event. <BR>
|
|
* - Upon getting new event, the debugger <BR>
|
|
* performs the check corresponding to the event. <BR>
|
|
* <BR>
|
|
* Note. To inform each other of needed actions, the debugger and <BR>
|
|
* and the debuggee use debuggee's variable "instruction". <BR>
|
|
* In third phase, at the end, <BR>
|
|
* the debuggee changes the value of the "instruction" <BR>
|
|
* to inform the debugger of checks finished, and both end. <BR>
|
