Hi,
With the little knowledge of Java I made the following modification in
org.apache.james.modules.mailbox.LuceneSearchMailboxModule
# add an extra includes
import com.google.inject.name.Names;
#add an additional line in the configure method
bind(Boolean.class).annotatedWith(Names.named("dropIndexOnStart")).toInstance(false);
These changes apparently solve the problem, but I don't think it should be
solved that way.
Best regards!
