I am occasionally getting the following exception:
java.util.ConcurrentModificationException
     at java.base/java.util.HashMap.computeIfAbsent(HashMap.java:1221)
     at org.exist.xmldb.DatabaseImpl.getRpcClient(DatabaseImpl.java:318)
     at org.exist.xmldb.DatabaseImpl.getRemoteCollection(DatabaseImpl.java:241)
     at org.exist.xmldb.DatabaseImpl.getCollection(DatabaseImpl.java:182)
     at org.exist.xmldb.DatabaseImpl.getCollection(DatabaseImpl.java:171)
     at org.xmldb.api.DatabaseManager.getCollection(DatabaseManager.java:235)
     at org.xmldb.api.DatabaseManager.getCollection(DatabaseManager.java:201)
Is xmldb supposed to be thread safe?  If so, does that HashMap need to be changed to a ConcurrentHashMap or some other type of external synchronization added to HashMap?  Thanks.

Bernard Harris
