Dbms_output doesn't output

Question

Hi,
Please try this in sql developer version 1.0.0.15.57
BEGIN
DBMS_OUTPUT.PUT_LINE('hi' || rpad('heyhey', 255, 'x'));
END;
Doesn't output anything, but this does.
BEGIN
DBMS_OUTPUT.PUT_LINE('hi');
END;
Both work in sqlplus. Is this a bug?
Thank you.

Not sure that this is a bug... dbms_output.put_line has a limit of 255 characters per line.
See this asktom link that explains it and gives a fix for it...

'hi' || rpad('heyhey', 255, 'x')) would be 255 characters plus 2 equaling 257.
Error starting at line 1 in command:
BEGIN
DBMS_OUTPUT.PUT_LINE('hi' || rpad('heyhey', 254, 'x'));
END;
Error report:
ORA-20000: ORU-10028: line length overflow, limit of 255 chars per line
ORA-06512: at "SYS.DBMS_OUTPUT", line 35
ORA-06512: at "SYS.DBMS_OUTPUT", line 133
ORA-06512: at line 2
When I change the rpad to 253 the output is fine and this nasty error doesnt show up. Using SQL Developer ofcourse the whole time.
Tried this with SQL Plus 9.2 database and got exact same error.. So, like I said.. Not a bug.. Normal for at least 9.2 database.
