问题
I am using mobilefirst 7.1 CLI and have my services running on tomcat. My adapter talks with the services on the servers and gets back the response. I have only desktopbrowser environment in the application (Guessing that should not matter at all).
I am getting this error
" failure. state: 500, response: The server was unable to process the request from the application. Please try again later."
And followed by :
Client registration failed with error: {"responseHeaders":{"$WSEP":"","Date":"Mon, 07 Dec 2015 17:00:58 GMT","Connection":"Close","Content-Type":"text/html;charset=UTF-8","X-Powered-By":"Servlet/3.0","Transfer-Encoding":"chunked","Content-Language":"en-US"},"status":500,"responseText":"\r\nhttp://www.w3.org/1999/xhtml\" xml:lang=\"en-US\" lang=\"en-US\">\r\n\r\n\r\n\r\nbody{\r\n margin:0px;\r\n padding:0px;\r\n background-color: #ffffff;\r\n color:#000;\r\n font-family:Arial,Verdana,Helvetica,Tahoma,sans-serif;\r\n}\r\n#content {\r\n font-size: 1em;\r\n margin-left: 1em;\r\n margin-right: 1em;\r\n padding: 1em;\r\n}\r\nh4.basichead {\r\n font-family:Arial,Verdana,Helvetica,Tahoma,sans-serif;\r\n}\r\np {\r\n padding-top: .5em;\r\n}\r\nul {\r\n line-height: 1.3em;\r\n}\r\na:link { \r\n color: #c00000 \r\n} \r\na:visited { \r\n color: #c00000 \r\n}\r\n#page { \r\n border: 7px; \r\n padding: 7px\r\n}\r\n#box { \r\n margin: 0; \r\n}\r\n#title {\r\n font-family:Arial,Verdana,Helvetica,Tahoma,sans-serif;\r\n font-size:24px;\r\n font-weight: normal;\r\n color:#274a71;\r\n padding-bottom:6px;\r\n}\r\n#error { \r\n colory: #c00004; \r\n margin-bottom: 10px;\r\n}\r\n#code { \r\n font-family: monospace; \r\n font-size: 8pt;\r\n}\r\n#stack { \r\n margin-left: 30px;\r\n}\r\n\r\n\r\n\r\n\r\n\r\n \r\n \r\n\n Exception thrown by application class 'org.apache.wink.common.internal.http.Accept.valueOf:139'\n\n\njava.lang.NullPointerException:

update
We have been running with MFPF 7.1 for a month now. This issue with the adapters (there are two of us with the same problem) has only happened over the last couple of days. The current version of Java that we are using is 8.
As well as failing from our browsers (the trace my colleague posted), I have tried testing the adapters using the MF CLI which also fails
$ mfp adapter call
Which adapter do you want to use? OrganisationAdapter
Which endpoint do you want to use? OrganisationAdapter/retrieveOrganisation
Enter the comma-separated parameters: 1
How should the procedure be called? GET
Outcome:
undefined:1

I got the same problem. Actually both, state 500 and the problem with adapter call. And in my case the problem also suddenly appeared. Literally, on 2nt of December evening everything was OK, next day morning this issue appeared.
My colleague got the same issue and he managed to solve it using the older CLI build. It seems also that Eclipse version works without any problems.
