JMX metrics containing quotes are lost

[tooptoop4]

I have this config:

jmxUrl: service:jmx:rmi:///jndi/rmi://localhost:{{ .Values.jmx.port }}/jmxrmi
lowercaseOutputName: true
lowercaseOutputLabelNames: true
ssl: false
rules:
- pattern: "debezium.([^:]+)<type=connector-metrics, context=([^,]+), server=([^>]+)>([^:]+)"
  name: debezium_metrics_$4
  labels:
    plugin: "$1"
    name: "$3"
    context: "$2"

jmx values like these are being exposed to prometheus (as expected):
,"debezium.oracle:type=connector-metrics,context=streaming,server=my-topicoracle,attr=QueueRemainingCapacity":81920
,"debezium.oracle:type=connector-metrics,context=streaming,server=my-topicoracle,attr=MiningSessionUserGlobalAreaMemoryInBytes":7595872

BUT issue is metrics like these were the values contain quotes are not being sent:
,"debezium.oracle:type=connector-metrics,context=streaming,server=my-topicoracle,attr=CurrentScn":"521761522525"
,"debezium.oracle:type=connector-metrics,context=streaming,server=my-topicoracle,attr=LastEvent":"position: {scn: 6533}, key: {"ID" : "421", "CONTRACT_NUMBER" : "redac", "ATTRIB4" : null}"

seems string type not supported:
#255
#586
#548
#266
#377
#606

Closing due to working as designed.
