I got it working as per my requirement, well almost. I get an NPE when I
try to set the additional fields for the JsonLayout but works when I don't
set the them. I went through the source code, I think I am doing it right
but may be not.
KeyValuePair.Builder kb1 = new
KeyValuePair.Builder().setKey("compact").setValue("true");
KeyValuePair.Builder kb2 = new
KeyValuePair.Builder().setKey("complete").setValue("false");
KeyValuePair[] additionalFields = new
KeyValuePair[]{kb1.build(),kb2.build()};
System.out.println(additionalFields.length);
JsonLayout.Builder jb = new
JsonLayout.Builder().setAdditionalFields(additionalFields); <-- This breaks
//JsonLayout.Builder jb = new JsonLayout.Builder(); <-- This works.
FileAppender.Builder fp = new
FileAppender.Builder().withFileName("/tmp/xpose.json.log").withAppend(true);
fp.setName("DEMO");
fp.setLayout(jb.build());
FileAppender fps = fp.build();
fps.start();
addAppender(fps);
#### Relevant part of the NPE ####
