Start processo with JSON using REST API

[bdot]

Hi, I know this may not be direct answer but take a look at

• JSON proces variables - any gotchas?
• UnitTests @ https://github.com/flowable/flowable-engine/blob/1ccb67e77dbae20f2f7ebb75230bb3c87b15dc30/modules/flowable-engine/src/test/java/org/flowable/engine/test/json/JsonTest.java

Goodluck!
