8.2.0 - REPLACENODE

Hi All - I just ran the REPLACENODE command on a cluster with 5 nodes in 
it.  I ran the command async, and it failed with:

{
   "responseHeader":{
     "status":0,
     "QTime":11},
   "Operation replacenode caused exception:":"java.util.concurrent.RejectedExecutionException:java.util.concurrent.RejectedExecutionException: Task org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor$$Lambda$52/1374786673@18107b06 rejected from org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor@2c993425[Running, pool size = 10, active threads = 10, queued tasks = 0, completed tasks = 0]",
   "exception":{
     "msg":"Task org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor$$Lambda$52/1374786673@18107b06 rejected from org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor@2c993425[Running, pool size = 10, active threads = 10, queued tasks = 0, completed tasks = 0]",
     "rspCode":-1},
   "status":{
     "state":"failed",
     "msg":"found [1234] in failed tasks"}}

Prior to running the command, each shard had two replicas.  Now some shards have 4, and some 3.  In addition the auto scaling policy of:
cluster-policy":[{
       "replica":"<2",
       "shard":"#EACH",
       "node":"#ANY"}],
seems to be ignored as many collections have the same node hosting multiple replicas.  Is this related to JIRA:
https://issues.apache.org/jira/browse/SOLR-13586

?
Thank you!
