        Description

        ...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
        [1.358s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
        [1.399s][info][gc] Full GC request for "Metadata GC Threshold" is ignored
        [1.440s][info][gc] Full GC request for "Metadata GC Threshold" is ignored

        This indicates that VM re-enters the CollectForMetadataAllocation VM op to perform that request more frequently than in can.
