  30  * DESCRIPTION
  31  *    This test implements GF08 scenario of test plan for General
  32  *    Functions:
  33  *        Do the following:
  34  *        Run simple java apllication with VM option '-verbose:gc'.
  35  *        Run the same application with JVMTI agent. The agent should
  36  *        set JVMTI_VERBOSE_GC with SetVerboseFlag. Check that outputs
  37  *        in stderr in both runs are equal.
  38  *    The test agent has a special input parameter 'setVerboseMode'.
  39  *    When VM runs the test class 'gf08t001' with
  40  *      '-agentlib:gf08t001=setVerboseMode=yes'
  41  *    option, then the agent calls SetVerboseFlag with
  42  *    JVMTI_VERBOSE_GC flag in Onload phase.
  43  *    The test's script wrapper runs the 'gf08t001' class twice.
  44  *    First time, with "setVerboseMode=yes" agent mode. Second
  45  *    time, with "setVerboseMode=no" agent mode and with
  46  *    "-verbose:gc" VM option. In both cases the output is
  47  *    searched for 'Full GC' string, unless ExplicitGCInvokesConcurrent
  48  *    is enabled and G1 or CMS GCs are enbled. If ExplicitGCInvokesConcurrent and
  49  *    either G1 or CMS GCs are enbled the test searches for 'GC' string in output.
  50  *    The test fails if this string is not found in the output.
