Symptoms

When running a set of packaged stored procedures that perform queries against SDO_GCDR.GEOCODE and GEOCODE_ADDR, the cursor count on the database side steadily increases until eventually the ORA-1000 error occurs:

  ORA-01000: maximum open cursors exceeded
  
Initially, this was observed from a production web application, which uses the Spring framework with Java to connect to the database.
Then, the problem reproduced from a Java testcase using Java and the Oracle JDBC driver to call these packaged procedures.
Later, the behavior reproduced simply by calling these packaged procedures in a loop from within an anonymous PL/SQL block in SQL*Plus.

This does not appear to be matter of the stored procedures improperly opening (and then failing to close) cursors from within the stored procedures' PL/SQL code itself. Rather, the stored procedures' PL/SQL code doesn't actually open any cursors (thus there's nothing to close). This is because the stored procedure code uses implicit cursors.
