    31  * DESCRIPTION

    32  *     This test performs checking for

    33  *         command set: Event

    34  *         command: Composite

    35  *         command set: EventRequest

    36  *         command: Set, Clear

    37  *         event kind: SINGLE_STEP

    38  *     Test checks that

    39  *         1) debuggee successfully creates SINGLE_STEP event request

    40  *            for particular threadID with attributes:

    41  *            depth=INTO, size=LINE

    42  *         2) expected SINGLE_STEP event is received when the thread

    43  *            in debuggee steps to the next line after breakpoint

    44  *         3) debuggee successfully removes event request

    45  *     Test consists of two compoments:

    46  *         debugger: singlestep002

    47  *         debuggee: singlestep002a

    48  *     First, debugger uses nsk.share support classes to launch debuggee,

    49  *     and obtains Transport object, that represents JDWP transport channel.

    50  *     Next, debugger waits for tested class loaded and gets methodID

    51  *     and location for expected single step event into invoked method.

    52  *     Then debugger waits for breakpoint reached with some thread

    53  *     and makes request for SINGLE_STEP event for this threadID.

    54  *     When event is received debugger checks if the received event is for

    55  *     expected request, thread, and location and has correct attributes.

    56  *     Then debugger removes event request.

    57  *     Finally, debugger disconnects debuggee, waits for it exited

    58  *     and exits too with proper exit code.

    59  * COMMENTS

    60  *     Test was fixed due to test bug:

    61  *     4797978 TEST_BUG: potential race condition in a number of JDWP tests
