Stackoverflow error when loading list in JPA

I am using JSF 2.1 and have a problem loading lists containing huge amounts of data. The data is fetched from a database via JPA, which basically looks like this: (just the relevant part, omitting getters and setters)

public class HostController {

    private List<Host> allHosts;
    @Inject
    private HostService hostService;

    public void beforeRenderLoadList(final ComponentSystemEvent event) {
        allHosts = hostService.findAll();
    }
}

This code is used in a metaevent preRenderView on the xhtml-page.

It is working for smaller amounts of data, but since the original table contains about 6500 entries, it throws a stackoverflow error.

Is there any way to lazy load this list or to work around the error?

    The problem has finally been solved by setting each entity's FetchType to LAZY!
