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