A java application that connects to a database via JDBC/Thin repeatedly calls a PL/SQL stored procedure that takes an ARRAY argument. The relevant Java code is:
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("ESDBO.ARRTEST_TBL", conn);
ARRAY newarray = new ARRAY(desc,conn,usrprofiles.toArray());
OracleCallableStatement cstmt = (OracleCallableStatement)conn.prepareCall ("{ call arrtest_proc( ? ) }");
cstmt.setARRAY (1, newarray);

This is slow, taking 10 secs for 40k of data.

SQL trace shows the following sql statement as many times as the array size.
SELECT INSTANTIABLE, supertype_owner, supertype_name, LOCAL_ATTRIBUTES
all_types WHERE type_name = :1 AND owner = :2
