Migrating HSQL to MySQL

I'm using the MySQL Migration Tool to migrate an Alfresco HSQL database to MySQL. My computer is a Windows XP box with 2.5 GB RAM. The JRE version is 1.6.0_16.

When I try to convert the database, I get these errors:

Connection jdbc:hsqldb:file:C:\alfrescoBU\alf_data\hsql_data\alfresco
The list of schema names could not be retrieved (error: 0).
ReverseEngineeringGeneric.getSchemata :Out of Memory

I've tried starting the migration tool by specifying a maximum heap size of 512m, but that has no affect, and I don't think setting the max heap is the answer anyway.

Does anyone have any suggestions?
