Can not login CCM server with OSLC API

Hello!
I have a very strange situation when trying to pass authetification when requesting service provider catalog from CCM server (v4.0.5). When I do a request to get cookies with such parameters:

  Method: POST
  URL: https://localhost:9443/ccm/authenticated/j_security_check?j_username=jts&j_password=jts
  Headers: [Cookie=JSESSIONID=3F3A52CD8DCA4F7B2672D75E193B158D, Accept-Charset=UTF-8, Content-Type=application/xml]
  Data:

I get a response with code 200:

Received response 200: {
    "userId": "jts",
    "roles": [
        "JazzAdmins"]
}

Another word I can connect to CCM server from the external application. But when I try to pass Jazz form based authentification as it's described in OSLC workshop:

  Method: POST
  URL: https://localhost:9443/ccm/oslc/workitems/catalog/j_security_check?j_username=jts&j_password=jts
  Headers: [Cookie=JSESSIONID=36CE341D4286A38C01A2CAC8537E67D3, Accept-Charset=UTF-8, Content-Type=application/xml]
  Data:

I get response code 400 and a strange error:

java.io.IOException: {"errorClass":"java.lang.IllegalArgumentException","errorCode":400,"errorTraceMarshall":[{"errorTraceFileName":"StringUtil.java","errorTraceClassName":"com.ibm.team.workitem.service.internal.oslc.util.StringUtil","errorTraceMethodName":"splitPair","errorTraceLineNumber":54},{"errorTraceFileName":"StringUtil.java","errorTraceClassName":"com.ibm.team.workitem.service.internal.oslc.util.StringUtil","errorTraceMethodName":"splitPair","errorTraceLineNumber":25},{"errorTraceFileName":"MediaRange.java","errorTraceClassName":"com.ibm.team.workitem.service.internal.oslc.util.MediaRange","errorTraceMethodName":"compareTo","errorTraceLineNumber":334},

I noted a message "token is expected to be in 'name\/value' format". I try to solve the problem a lot of time but can not pass the authentification for "oslc/workitems/catalog" document.
An interesting moment, when I do the same with Firefox Poster plugin - the request works perfect.

I will appreciate any help regarding this issue! Please, help if somebody khows the reason of the issue!
Thank you very much in advance!
