 * @summary converted from VM Testbase nsk/jvmti/scenarios/general_functions/GF08/gf08t001.
 * VM Testbase keywords: [quick, jpda, jvmti, onload_only_logic, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *    This test implements GF08 scenario of test plan for General
 *    Functions:
 *        Do the following:
 *        Run simple java apllication with VM option '-verbose:gc'.
 *        Run the same application with JVMTI agent. The agent should
 *        set JVMTI_VERBOSE_GC with SetVerboseFlag. Check that outputs
 *        in stderr in both runs are equal.
 *    The test agent has a special input parameter 'setVerboseMode'.
 *    When VM runs the test class 'gf08t001' with
 *      '-agentlib:gf08t001=setVerboseMode=yes'
 *    option, then the agent calls SetVerboseFlag with
 *    JVMTI_VERBOSE_GC flag in Onload phase.
 *    The test's script wrapper runs the 'gf08t001' class twice.
 *    First time, with "setVerboseMode=yes" agent mode. Second
 *    time, with "setVerboseMode=no" agent mode and with
 *    "-verbose:gc" VM option. In both cases the output is
 *    searched for 'Full GC' string, unless ExplicitGCInvokesConcurrent
 *    is enabled and G1 or CMS GCs are enbled. If ExplicitGCInvokesConcurrent and
 *    either G1 or CMS GCs are enbled the test searches for 'GC' string in output.
 *    The test fails if this string is not found in the output.
