NameError, missing class name com.ibm.mq.jms.MQQueueConnectionFactory

Elastic Stack Logstash

Hello,

I have a JMS plugin configuration with purpose of connecting to IBM MQ. After starting the pipeline I get:

> 
> [WARN ] 2023-05-31 10:38:14.348 [[main]<jms] jms - JMS Consumer Died {:exception=>"NameError", 
> :exception_message=>"missing class name (`com.ibm.mq.jms.MQQueueConnectionFactory')",

> "/u01/logstash/logstash-core/lib/logstash/java_pipeline.rb:400:in `block in start_input'"]}

In the config I have included a reference to the correct jar's (I believe):

input {
  jms {
    ...
    factory => 'com.ibm.mq.jms.MQQueueConnectionFactory'
    pub_sub => false
   ...
    require_jars => ['/u01/logstash/logstash-core/lib/jars/javax.jms.jar',
                     '/u01/logstash/logstash-core/lib/jars/java-json.jar',
                     '/u01/logstash/logstash-core/lib/jars/com.ibm.mqjms.jar',
                     '/u01/logstash/logstash-core/lib/jars/com.ibm.mq.allclient-9.3.2.0.jar'
                    ]

    ...
}

In short: the missing class name IS present in the com.ibm.mq.allclient-9.3.2.0.jar but logstash complains about it missing. If I remove that jar, I get "class def not found" but if I have the jar added I get the above error.

What do I overlook?
