* The test checks that the JDI method
|
|
* <code>com.sun.jdi.request.EventRequestManager.stepRequests()</code>
|
|
* properly returns all StepRequest objects when:
|
|
* <li>event requests are disabled
|
|
* <li>event requests are enabled<br>
|
|
* A debuggee part of the test creates several dummy user and daemon
|

|
|
* EventHandler was added as workaround for the bug 4430096.

|
* This prevents the target VM from potential hangup.
