Amin Kechaou reopened DIRSERVER-1954:
-------------------------------------


Hi,
I am testing the version 2.0.0-M16 and it seems that jira https://issues.apache.org/jira/browse/DIRSERVER-1954
is not completely fixed.
Here are the steps to get the issue:
1.	I installed a server apacheDS based on the zip apacheds-2.0.0-M16.tar.gz from http://directory.apache.org/apacheds/downloads.html
2.	I slimmed it down (removed code for creating partitions/indices) so it only starts a DirectoryService
and LdapServer. I will attach the source code of the class.
3.	The first run goes as expected.
4.	Then I stop the process by doing kill -9 or by stopping the virtual machine which holds
the server.
5.	The second run always fails with the following error:

[18:06:35] ERROR [org.apache.directory.server.UberjarMain] - Failed to start the service.
org.apache.directory.api.ldap.model.exception.LdapEntryAlreadyExistsException: ERR_250_ENTRY_ALREADY_EXISTS
ou=system already exists!

                at org.apache.directory.server.core.DefaultDirectoryService.initializeSystemPartition(DefaultDirectoryService.java:1749)
                at org.apache.directory.server.core.DefaultDirectoryService.initialize(DefaultDirectoryService.java:1809)
                at org.apache.directory.server.core.DefaultDirectoryService.startup(DefaultDirectoryService.java:1244)
                at org.apache.directory.server.ApacheDsService.initDirectoryService(ApacheDsService.java:323)
                at org.apache.directory.server.ApacheDsService.start(ApacheDsService.java:182)
                at org.apache.directory.server.UberjarMain.start(UberjarMain.java:76)
                at org.apache.directory.server.UberjarMain.main(UberjarMain.java:54)
[18:06:35] DEBUG [org.apache.directory.server.core.DefaultDirectoryService] - +++ DirectoryService
Shutdown required


The third run will be smooth again.So will the fourth, fifth, etc.

Regards

> Then I stop the process by using the square red button in the console window of Eclipse.
I will add a screenshot. I think this will kill the JVM, but I am not sure.
