Get stuck at creating producer without any error or response

[fearless-bz]

I write a log4jPulsarAppender in order to submit logs directly into the pulsar topic however it doesn't work. When I try to initialize a pulsar producer using the 'producerBuilder.create()' method, no response is returned or no error is thrown, instead the process is stuck.


Do you have any idea about what's wrong with this creation? Thank you so much.
