I am facing issues with one of the bitbucket-server Java APIs. How do I report/raise this issue?
Currently the only way to report a bug is through support.atlassian.com. Figure out a way to express it through a customer’s perspective and report it that way. It’s not ideal but the only way nowadays unfortunately. 
If you share what the problem is here maybe somebody here might know of a workaround.
Can you give us some more insight into the exact issue you have?
