Why i can't create JS object from literal and add properties to it;

Try in scripted data set on open:

var o = {};
o["p"] = 123;

Have exception: Java class "java.lang.Object" has no public instance field or method named "p";

BIRT version 4.3.1

This script works for me, with Eclipse 4.3.1.

May be the exception is due to the fact you rely this object "o" would be available in methods "fetch" or onFetch" of your scripted dataset, but you scoped it with "var" so it is local to the method. You should try to remove "var"

As i said it works for me, even in the open handler of a scripted dataset or anywhere else. See report attached.

You should post a sample report highlighting the issue.
