Bug in PUT template

[jnehring]

I called http://api-dev.freme-project.eu/current/e-link/templates/77?token=a2baa132-da71-4cb9-b87a-e460bc67b168&informat=json&outformat=json with body

 {
 "query":"a SPARQL CONSTRUCT query",
 "endpoint":"http://abc.de",
 "label":"THE title of the template",
 "description":"a description of the template"
 } 

The changes are saved but the return value is

{
    "exception": "eu.freme.broker.exception.InternalServerErrorException",
    "path": "/e-link/templates/77",
    "message": "Unknown problem. Please contact us.",
    "error": "Internal Server Error",
    "status": 500,
    "timestamp": 1444312793337
}

Some parts of the broker log:
