This is related to the messed up CORS implementation by atlassian. If you make something else as a GET request, e.g. (POST, PUT, DELETE) the browser performs a pre-flight request. This is a HEAD request checking if the requested resource allows for the method and specific headers. Unfortunately on a lot of Atlassians products these headers are not set properly. We addressed this by wring a add-on containing a servlet filter for all desired resources that handles pre-flight requests and allows the proper headers.
