Discrepancy in behavior between white and black listing hosts in FilteredForestConfiguration

[srinathgit]

I see a discrepancy between the behavior of withWhitelist and withBlacklist methods. I create the client using hostname "rh7v-intel64-90-test-16" . The other hosts in the cluster are rh7v-intel64-90-test-17.marklogic.com, rh7v-intel64-90-test-18.marklogic.com.

1. When I blacklist "rh7v-intel64-90-test-16.marklogic.com", the forest configuration is

11:54:59.994 [main] INFO c.m.c.d.impl.WriteBatcherImpl - (withForestConfig) Using [rh7v-intel64-90-test-17.marklogic.com, rh7v-intel64-90-test-16, rh7v-intel64-90-test-18.marklogic.com] hosts with forests for "WriteHostBatcher"

2. When I whitelist "rh7v-intel64-90-test-16.marklogic.com", the forest configuration is

11:45:26.494 [main] INFO c.m.c.d.impl.WriteBatcherImpl - (withForestConfig) Using [rh7v-intel64-90-test-16.marklogic.com] hosts with forests for "WriteHostBatcher"
