Parameter is not formatted correctly: ":splunk:event:1.0; charset=utf-8" for: "application/json; profile=urn:splunk:event:1.0; charset=utf-8"

[ghost]

I tried to create HttpEventCollectorLogbackAppender programmatically, but it is not working.

After some debugging i hopefully found the reason.
The MediaType seems to be not formatted correctly.

How can i fix this?

java.lang.IllegalArgumentException: Parameter is not formatted correctly: ":splunk:event:1.0; charset=utf-8" for: "application/json; profile=urn:splunk:event:1.0; charset=utf-8"
