Concurrency issue in /service/rest/maven/download REST API

The "/service/rest/maven/download" can fail with the following exception:

2021-11-08 12:40:32,787-0500 ERROR [qtp314753310-53276] *UNKNOWN com.vestmark.nexus.plugin.maven.MavenResource - storageTx response exception:
java.lang.IllegalStateException: The current database instance (com.orientechnologies.orient.core.db.OPartitionedDatabasePool$DatabaseDocumentTxPooled@7e0275e3) is not active on the current thread (Thread[qtp314753310-53276,5,main]). Current active database is: null

This seems to be correlated with running a "Repair - Rebuild Maven repository metadata" task at the same time the API is called.
