Symptoms
A query: select * from table where col1 = 372223, with a non-unique index on col1, runs slow in sql developer.
The execution time is average 20 ms in sqlplus (or toad) and average 30 sec in sql developer.
On repeating the query in sql developer it also becomes fast, until the query is changed (and has to be reparsed).
