[0.968s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[0.983s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[1.000s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[1.161s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[1.211s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
