If you need to increase the memory, find the eclipse.ini and change maximum Xmx memory (-Xmx512m):
find /Applications/ide/eclipse/Eclipse.app
open /Applications/ide/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini
if you use a TextWrangler it will open it by default.

NOTE:
Before you go and start increasing available memory please take a look at your code and refractor ANY creation of objects from inside loops, or at least heavy objects like database Statement used in the inserts:
Connection connection = MySqlHelpers.makeDbConnection(db, user, password);
Statement statement = connection.createStatement();
Just removing the Statement from the loop stabilized java process "Real Memory" footprint growth at 61 MB. Removing various Strings variables made much smaller difference.
I noticed that few System.out.println(...) does not really increase the memory footprint.
