The sample code does not run and exits without any error.

On branch 2.2.x, after installing all spring-data-orientdb modules (mvn clean install -DskipTests) from the root of the project, I just started the sample hello word:

mvn spring-boot:run

Then, in a browser:

http://localhost:8080/persons

that gives:

[

id: "#33:0",
firstName: "Graham",
lastName: "Jacobson",
age: 25
},
{
id: "#34:0",
firstName: "Ebony",
lastName: "Irwin",
age: 21
},
{
id: "#35:0",
firstName: "Benedict",
lastName: "Preston",
age: 25
},
{
id: "#36:0",
firstName: "Zorita",
lastName: "Clements",

},
{
id: "#37:0",
firstName: "Kaitlin",
lastName: "Walter",
age: 22
}
]

I followed the same instructions on Windows and it worked. For some reason, it did not work on my Ubuntu environment. Not sure what the issue is with Ubuntu/Linux.
