> There is a sporadic NullPointerException in the SaslBindIT tests. First, it 
> didn't occur on my Mac, but on Linux and Windows CI builds. Now I created a 
> test that binds 1000 times (sequential) with CRAM-MD5, Digest-MD5 and GSSAPI, 
> and I can reproduce the exception on my Mac.
> Most time the exception occurs during a GSSAPI bind, but also sometimes 
> during a Digest-MD5 for Cram-MD5 SASL bind.
> Here is the thrown exception:
> java.lang.NullPointerException
>       at 
> org.apache.directory.ldap.client.api.LdapNetworkConnection.bindSasl(LdapNetworkConnection.java:3534)
>       at 
> org.apache.directory.ldap.client.api.LdapNetworkConnection.bindSasl(LdapNetworkConnection.java:3437)
>       at 
> org.apache.directory.ldap.client.api.LdapNetworkConnection.bindDigestMd5(LdapNetworkConnection.java:1213)
>       at 
> org.apache.directory.ldap.client.api.LdapNetworkConnection.bindDigestMd5(LdapNetworkConnection.java:1239)
>       at 
> org.apache.directory.ldap.client.api.LdapNetworkConnection.bindDigestMd5(LdapNetworkConnection.java:1192)
>       at 
> org.apache.directory.server.operations.bind.SaslBindIT.testSequentialBinds(SaslBindIT.java:439)
> Before the exception is thrown the test hangs for some time. The BindFuture 
> then times out and returns null. Is that a problem with available resources?
