Creating a Sequence with Mixed Case Name vs UPPER CASE name Problem

I have noticed with HANA, that it appears to be lenient with the case of Column and table names (ie, lower, UPPER, MiXeD cases); however, there does seem to be an issue when creating a sequence with Mixed case.

If I do

create sequence "acl_sid_KEY_SEQ" increment by 1 start with 1 no cycle ;

SELECT ACL_SID_KEY_SEQ.NEXTVAL from DUMMY;

SELECT acl_sid_KEY_SEQ.NEXTVAL from DUMMY;

Both selects will fail:

Could not execute 'SELECT ACL_SID_KEY_SEQ.NEXTVAL from DUMMY' in 21 ms 897 µs . SAP DBTech JDBC: [313] (at 7): invalid sequence: ACL_SID_KEY_SEQ: line 1 col 8 (at pos 7)

Could not execute 'SELECT acl_sid_KEY_SEQ.NEXTVAL from DUMMY' in 21 ms 903 µs . SAP DBTech JDBC: [313] (at 7): invalid sequence: ACL_SID_KEY_SEQ: line 1 col 8 (at pos 7)

However, if I keep the case of the sequence all upper case, I can do:

create sequence "ACL_SID_KEY_SEQ" increment by 1 start with 1 no cycle ;

SELECT ACL_SID_KEY_SEQ.NEXTVAL from DUMMY;

SELECT acl_sid_KEY_SEQ.NEXTVAL from DUMMY;

Both selects return with 1, then 2 respectively.

Is this a bug?
