* 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 'Pause Full' string, unless ExplicitGCInvokesConcurrent
* is enabled and G1 is enabled. If ExplicitGCInvokesConcurrent and
* G1 is enabled the test searches for 'GC' string in output.
* The test fails if this string is not found in the output.
