> Situation in which the error occurs:
> When shutting down server of Product X (which embeds Apache Directory Server) we
> have some problems with shutting down the embeded LDAP server. One of the
> reasons could be the addShutdownhook in RootNexus.java. When embedding the
> LDAP server we need to add a shutdownhook ourselves to make sure the LDAP
> server is gracefully shutdown (see code below). Among other things, the
> shutdown of the embedded LDAP server seems to call the sync on the
> RootNexus as well, causing an IllegalStateException as 2 separate threads
> are accessing the RootNexus.
> Java API for System.exit:
> The virtual machine's shutdown sequence consists of two phases. In the
> first phase all registered shutdown hooks, if any, are started in some
> unspecified order and allowed to run concurrently until they finish.
> Example of shutting down (which is implicitly a part of our shutdownhook):
> Properties env = new Properties();
> env.setProperty(Context.PROVIDER_URL, "ou=system");
> env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
> "org.apache.ldap.server.jndi.ServerContextFactory");
> env.setProperty(Context.SECURITY_PRINCIPAL, "uid=admin,ou=system");
> env.setProperty(Context.SECURITY_CREDENTIALS, "secret");
> env.setProperty(EnvKeys.SYNC, "true");
> env.setProperty(EnvKeys.SHUTDOWN, "true");
> new InitialDirContext(env);
> Maybe this is caused by the soluttion for bug report
> http://issues.apache.org/jira/browse/DIREVE-92?
> I'm capable of reproducing this behavior in a small program which is attached.
> The program will ask for input (via System.in.read). When asked for input, please press Control-C to exit. The program will call the shutdown hook multiple times and will result in a 'Failed to sync all'.
