Description
Unable to add message board attachment via JSON

Changed the JSONWS API. New steps to reproduce/test:
1. Start Liferay and login as admin
2. Go to

{domain}/api/jsonws?contextName=&signature=%2Fmbmessage%2Fadd-message-7-groupId-categoryId-subject-body-fileName-file-serviceContext
groupId: groupId of Guest group
categoryId: 0
subject: any string
body: any string
fileName: any valid file name with file type
file: any file
3. Go to Site Administration > Message Boards

Expected results: Results tab shows the MBMessage created. Navigate to Site Administration > Message Boards. It should contain the MBMessage with the file attached.

Old steps, not applicable!
Steps to reproduce/Testing done
# Start Liferay and login as admin
# Go to {domain}

/api/jsonws?signature=%2Fmbmessage%2Fadd-message-10-groupId-categoryId-subject-body-format-inputStreamOVPs-anonymous-priority-allowPingbacks-serviceContext

1. • groupId: Enter the Site ID located in the Site Settings
   • categoryId: 0
   • Subject: Any string
   • Body: Any string
   • Format: html
   • inputStreamOVPs: [ {key: 'fileName.txt', value: [84,104,105,115,32,105,115,32,97,32,116,101,115,116,32,116,101,120,116,32,102,105,108,101,46]}

     ]

   • Anonymous: Any boolean value
   • Priority: 0
   • allowPingbacks: Any boolean value
2. Hit Invoke
3. Receive the following error:

   "Unable to convert to type: com.liferay.portal.kernel.util.ObjectValuePair"

If inputStreamOVPs is set to:
[]
The post submits successfully.

To verify if the attachment has been uploaded successfully:

1. Go to Site Administration and click on "Message Boards" under "Content"
2. Click on the title of the message boards entry
3. Click on the attachment (should have the name fileName.txt for the example inputStreamOVPs above)
4. For the example above, verify that the contents are "This is a test text file."

Results of Testing
Expected behavior: The message board post and attachment is added
Actual behavior: An error is returned and the post and attachment is not added
