Sporadic NullPointerException during SASL bind
----------------------------------------------
Key: DIRAPI-30
URL: https://issues.apache.org/jira/browse/DIRAPI-30
Project: Directory client API
Issue Type: Bug
Affects Versions: 0.2.0
Reporter: Stefan Seelmann
Fix For: 0.2.0
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?
