Why is Output different every time? try catch finally exception code

Question

class TestExceptions {

    public static void main(String[] args) throws Exception {
        try {
            System.out.println("try");
            throw new Exception();
        } catch(Exception e) {
            System.out.println("catch");
            throw new RuntimeException();
        } finally {
            System.out.println("finally");
        }
    }
}

Following are the outputs when I try to run the code in eclipse multiple times. I believed so far that whenever the last line of the code from either try/catch block is about to be executed (which could be return or throws new Exception() type of stmt), finally block will be executed, but here the output different every time? Can anyone clarify if my assumption is right or wrong?

try
catch
Exception in thread "main" finally
java.lang.RuntimeException
    at TestExceptions.main(TestExceptions.java:9)


Exception in thread "main" try
catch
java.lang.RuntimeException
    at TestExceptions.main(TestExceptions.java:9)
finally

This is clearly because eclipse is printing the error stream and output stream without proper synchronization in console. Lot of people have seen issues because of this.

Execute the program in a command prompt and you will see proper output every time.
