Bug #20912 DatabaseMetaData.getTables hangs/memory leaks

Description:
Trying to list tables on a non-default catalog causes a hang and memory leak. For example, when the default catalog is "inventory" (specified in the URL for creating the connection): 

getTables("orders", null, "%", tableTypes) hangs and memory usage starts to grow very large... 

Also, 
getTables("orders", null, "shipto", tableTypes) hangs and memory usage starts to grow... 

The "orders" catalog and "shipto" table both exist.

As a work-around, I tried to pass null as the catalog and just pick out those tables with a matching catalog name. But, instead of listing all tables for all catalogs, it only lists tables in the default catalog (another bug). Thus, there is no work-around to get a listing of tables outside the default catalog.

This is critical issue because most large applications access across catalogs. For example, data in "accounts" recievables/payables might be updated when  "orders" or "inventory" are updated.

I was using Connector/J 3.1.3 with MySQL 5.0.

How to repeat:
Into some existing program you already have, insert a statement that calls getTables specifying a non-default catalog name and use a wild card ("%") for the table name parameter.
