WARNING: The system property 'mail.mime.decodeparameters' is not set to true. This may result in e-mail attachments with non-Latin filenames being dropped.

Dear Support,

We have got the warning message below thats why our e-mail notification does not work. We checked the registry and the related property seems set true already. Could you please help us to fix the problem?

For your case, I believe that setting does not reflect properly from your description. Would you try to investigate further referring to the below documentation to see if this is the case for your problem?

Do take note on the resolution that

Ensure that each defined parameter is defined on its own line.
Ensure that there are no extra spaces at the end of the parameters.

Just sharing this in case of other customer bump into the same issue :)

It might be in the registry, but Java is system independent and doesn't care about the registry unless you specifically code to read it. It only reads the environment (which is partly generated from the registry on windows boxes, but often badly or not at all)

Go into your Jira/Confluence/Whatever "system information" page and look for mail.mime.decodeparameters - if it's not there on the page, then it's not set in the environment.

You need to make sure the environment that Java runs in contains "-Dmail.mime.decodeparameters=true" or just "mail.mime.decodeparameters=true". Have a look at the environment for the service process running it.
