I can't get the Bug_Submitter to successfully submit a bug report. I don't know if it might be a proxy server issue, but here is what I investigated:

(I have configured Fiji to use system proxy settings. The same behaviour is observed with the proxy configured manually in Edit>Options>Proxy Settings...)

When submitting a bug report ('Submit Bug Report'), I get the message:
"The login failed: your username or password may be incorrect."

I knew that my login credentials are correct, so I looked for "LOGIN_FAILURE" in the source and found two occurences:

https://github.com/fiji/Bug_Submitter/blob/master/src/main/java/Bug_Submitter/Bug_Submitter.java#L205
https://github.com/fiji/Bug_Submitter/blob/master/src/main/java/Bug_Submitter/Bug_Submitter.java#L227

Apparently I get no cookie response and hit the first of these (line 205), which I found out by changing it to OTHER_FAILURE.

The http response serves the bug submission page as expected (I found out by logging the connection.getInputStream()), so I guess the connection works correctly, all I miss is the cookies that apparently should be set but aren't.

Thanks for any advice on this.
