java.lang.OutOfMemoryError collecting process configuration data from Eclipse client

We have created an aspect editor to edit the process configuration elements for an operation participant we contribute via a plug-in.  When the aspect editor is opened, it displays a progress monitor while it collects data for the project areas to which the Eclipse client is connected.  For each project area, it gathers data such as the work item types defined in the project area, the attributes and enumerated values, link types etc.  for display on the various dialogs that the user can open to configure the configuration elements for the operation participant.  We have a particular customer - the only customer who has experienced this problem - who is getting an OutOfMemoryError while the aspect editor is collecting the data.  His Windows Task Manager shows that eclipse has used 643,548K of memory during the opening of the aspect editor.  Ultimately, he gets the OutOfMemoryError as shown below.  Is this just a simple case of not having enough memory allocated for his Eclipse client, or is there some other reason for this failure?



So I clicked Yes and looked at .log and saw this:
