...otherwise there is a flurry of GC messages like this, because metaspace is not resized in bulk:
[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
[1.232s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[1.262s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
[1.281s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
