Hi Rick,
The problem is HttpURLConnection does not support the sending of
request entities for a DELETE request, and Jersey is masking that
error as a consequence of attempting to recover. So i need to fix that
error reporting. Could you log an issue?
I really do not know why HttpURLConnection has such a restriction.
You should be able to switch to using the Apache HTTP client, which
IIUC does not have such a restriction:
https://jersey.dev.java.net/nonav/apidocs/latest/contribs/jersey-apache-client/com/sun/jersey/client/apache/package-summary.html
Thanks,
Paul.
