Subject Distinguish null vs unspecified value in java
Date Tue, 01 Jan 2013 01:28:10 GMT

Per section 5.2 of thrift white paper "When an expected field is not
found, there must be
some way to signal to the developer that it was not present".

Considering the above, I was wondering if there is anyway to
distinguish null vs an unspecified value in java? As far as I can tell
current implementation treats both as null which mean we can't add any
new nillable field without breaking forward compatibility.
