Hi @joaopalma5 -- I merged a change to the code in question on L168 that may resolve this error! If you would be so kind as to re-run your tests and see if it's resolved, that would be great! :) Thank you so much.

@celanthe , the problem is when is sending or receiving... Not is in the assert.

I set this option: session.setDebug(true); and I get this output:

Based in output, I think the error it is in received part... What you think?

@celanthe You run the test in your computer? What is the output?

[celanthe]

Hi @joaopalma5 -- I've not run it on my machine. My above fixwas made in an effort to resolve the error on L168 in https://github.com/camunda-community-hub/camunda-bpm-mail/blob/master/extension/core/src/test/java/org/camunda/bpm/extension/mail/poll/PollMailConnectorTest.java#L168 where (to me, at least...) it appears that the <b> and </b> tags may be causing an issue.

I will look into this further and get back to you ASAP! :)

[joaopalma5]

I made more tests, I will share bellow:

In https://github.com/camunda-community-hub/camunda-bpm-mail/blob/master/extension/core/src/main/java/org/camunda/bpm/extension/mail/poll/PollMailResponse.java#L72 , put this method:

 public void exp(){
    System.out.println("xpto");
    try {
      Multipart mp = (Multipart) messages.get(0).getContent();
      System.out.println("------------------ 1st Part ---------");
      MimeBodyPart mbp = (MimeBodyPart) mp.getBodyPart(0);
      System.out.println(mp.getBodyPart(0).getContentType());
      System.out.println(mbp.getContent());
      System.out.println("------------------ 2nd Part ---------");
      System.out.println(mp.getBodyPart(1).getContentType());
      System.out.println(mp.getBodyPart(1).getContent());
    } catch (IOException e) {
      e.printStackTrace();
    } catch (MessagingException e) {
      e.printStackTrace();
    }
  }

And Call in https://github.com/camunda-community-hub/camunda-bpm-mail/blob/master/extension/core/src/test/java/org/camunda/bpm/extension/mail/poll/PollMailConnectorTest.java#L163, like:

response.exp();

Will get:

The type is correct but I can't obtain the content.

Hello @celanthe, just want to let you know that the assert in PollMailConnectorTest is failing with:

org.junit.ComparisonFailure: 
Expected :"html"
Actual   :"<b>html</b>"

Reverting the change in faf629c commit would fix it.

[celanthe]

Hi @standev! Thank you kindly for the clear advice. I have reverted the commit in question. :) @joaopalma5, I hope this helps!

[jonathanlukas]
