> Client was requesting table configuration, which locks a hash map at ServerConfigurationFactory.java:155,
and that proceeds to try and get a lock on the ServerConfiguration class (ServerConfiguration.java,
36). That lock was held by a BulkImport request which was reading ServerConfiguration, which
was trying to get a lock on the HashMap (ServerConfigurationFactory.java:48).
> Unfortunately, I cannot (easily) reproduce the stack traces here.
