Eclipse tooling: CDE fully instantiates components of aggregates, resulting in OutOfMemory issues

When I create an aggregate descriptor from several installed pears (e.g., WS tokenizer, tagger & regex), the CDE creates an OOM situation on Eclipse 3.5 and Sun Java 6 on windows. This seems to be due to the fact that the CDE fully instantiates delegate components to get at their metadata. Is this really necessary? We keep all our metadata in xml specifically so we don't have to do this.
