Missing delete of directory or useless code?

[Felix Knecht]

ApacheDS Core Annotations
org.apache.directory.server.core.factory.DefaultDirectoryServiceFactory 
Line 219:

Comment says
"Erase the working directory to be sure that we don't have some 
remaining data from a previous run",
but all what is done is
"String workingDirectoryPath = 
directoryService.getInstanceLayout().getInstanceDirectory().getPath();"

Looks not very logical to me. Any ideas?

Thanks
