---------------------------------------
The latest code from SVN does not seem to work, I get this error when trying to
use JSONLayout:

> Better structure of Thread Context Map in JSONLayout
> ----------------------------------------------------
>
> Key: LOG4J2-623
> URL: https://issues.apache.org/jira/browse/LOG4J2-623
> Project: Log4j 2
> Issue Type: Improvement
> Components: Layouts
> Affects Versions: 2.0-rc1
> Reporter: Mikael Ståldal
> Assignee: Ralph Goers
> Priority: Minor
> Fix For: 2.0-rc2
>
>
> Currently, the Thread Context Map looks like this in JSONLayout:
> {code:JavaScript|title=Current}
> "Properties":[
> {
> "name":"UserName",
> "value":"admin"
> },
> {
> "name":"OrgName",
> "value":"test"
> }
> ]
> {code}
> This does not properly make use of the JSON data format. Since the Thread
> Context Map is a map, it should be represented as a JSON object. And why not
> name it "mdc" rather than the quite vauge "Properties"?
> {code:JavaScript|title=Suggested}
> "mdc": {
> "UserName":"admin",
> "OrgName":"test"
> }
> {code}
