--------------------------------------
[~larsh] I think I messed up in the repro steps.
The issue is when a column with type CHAR(N) has a value less N bytes.
{code:java}
0: jdbc:phoenix:localhost:52919> UPSERT INTO TEST.TABLE_WITH_VARCHAR(ID) VALUES
('00000000000000');

0: jdbc:phoenix:localhost:52919> UPSERT INTO TEST.TABLE_WITH_CHAR(ID) VALUES
('00000000000000');
